Can I Paint Over Powder Coated Rims?
Yes, you can, but the process won’t be as straightforward or harmless as it seems. So you need to consider some factors and prepare well.
While powder coats are extremely durable, they aren’t invulnerable. If the coat is chipped, scratched, or dented, it can be tempting to spray over the blemish and call it a day. But this might cause some problems.
Firstly, the area where the powder coat is thinner won’t be as well-protected (even with an added paint coat), leaving it open to more damage. And secondly, depending on the width and depth of the damage, spraying over it might cause an unsightly warped look.
For the primer and paint to apply well, the rim must be clean of dirt, dust, and grease. Next, you’ll need to use fine grade abrasive paper to sand down the powder-coated surface.
This step is vital to the process as powder coating has a smooth finish that paints and primers won’t stick to. However, sanding down a powder coat can negatively affect its performance, so consider carefully.
For the best outcome, you’ll need a primer made for the surface. You’ll also need to test its adhesion. To do so, apply a small spot of primer to the rim and wait 30 mins for it to dry. If the dried primer comes off easily, you’ll need to sand down the powder surface some more.
Once the primer is dry, you can start painting. Epoxy-based paints will usually have no trouble sticking to most surfaces, but enamel paints are often a cheaper alternative. Additionally, enamel paints adhere better to primers made for metal-alloy surfaces, leading to better overall performance.
So while it’s not hard to spray over powder coated wheels, in some cases, it’s best to start with a bare surface.
And if you want your powder coat safely removed (or are just looking for an expert respray job), Wheels Respray is here to deliver.
Respraying vs Powder Coating Wheels: What’s the Best Option?
Respraying and powder coating each have their pros and cons. So here’s a breakdown to help you decide what’s the best option for you.
Powder coating is a more environmentally friendly option than respraying. Firstly, paints are high in harmful Volatile Organic Compounds, chemicals that contaminate the environment. But as powder coats don’t contain solvents, they have low VOC levels (and sometimes none at all).
And secondly, powder coating wheels produces almost no waste as the powders can be reclaimed and reused. Meanwhile, any paint overspray will be lost forever.
Depending on the paint’s thickness and composition, a respray will effectively protect your rims from scratch damage and rust.
But, powder coats are a more durable alternative. They offer greater protection for your wheels, and will last longer due to a higher scratch resistance (4H compared to spray’s H).
Spray painting can achieve some awesome custom designs. Paint can also be applied in a thinner layer, so it generally won’t affect the shape of your rims.
However, custom powder coating (while requiring a more involved apply-cure-mask-apply process) isn’t that far behind. And even though it's applied in a thicker coat, the curing process ensures the coat will be completely even, which is difficult to achieve with paint. Not to mention powder coats have a wider range of finishes and don’t fade easily.
But whether you decide on a respray or powder coat, the best option for either is to get it done by the experts. Get in touch with us, and we’ll handle your rims’ powder coating or respray needs.
Can You Powder Coat Rims That Aren’t Bare?
t is possible to apply powder coating to rims already coated in, for example, paint.
However, there are some things you need to consider before you start.
Powder coatings don’t dry on their own. To fully harden and do their job well, they need to be cured at around 120-200 c, which many coatings (e.g., plastics and rubber) can’t withstand.
Unlike with clear bras, powder coating will completely cover and obscure whatever it’s applied over.
Powder coats are already applied pretty thick, at an average of 6-10 mm. So if they’re applied over an existing coat or two of paint, you can expect a build of at least 8 mm, which will affect the overall shape of the rims.
The thickness of the underlying coat will also affect how well the powder coat adheres to your rims. If the existing coat is 3 mm thick or more, even experts will have trouble grounding the powder coat as it relies on electrostatic adhesion and thus applies best to a surface that can hold a charge (e.g., metal).
Because powder coats adhere best to bare rims, applying them over existing coats may negatively affect the powder’s durability, leaving your wheels less protected and opening the doors to chips, scratches, and water damage.
At the end of the day, if you want the most out of your powder coat, you’ll need to go in bare. Fortunately, our team of experts can safely remove any undercoats.

How do you clean powder coat?
There are a lot of products that can be powder coated, but none more so than automotive parts. Powder coat is known to have electrostatcially charged particles that make them bond with metal, therefore giving it a more durable coating than those with ordinary paint. Although it will make powder coated items last longer, powder coating does not make your rims invulnerable. You will still need to take care of the coating, so here’s a guide on how to clean powder coated surfaces.
As with everything, you should try to make sure that your powder coated wheels are always free from dust or debris. This is why when asking how do you clean powder coat, you should always consider your location. There will be areas that will be more susceptible to pollutants, like the the beach’s mixture of saltwater and sand, or the polluted and grimy air of the city. Some areas will require you to clean your powder coated rims as often as possible, and some will require washing within a week or two.
Here’s a general idea on how to remove stains from powder coat: wet the area to loosen up any dirt or debris sticking to the rims. With a wet sponge, carefully wipe the area to remove any deposits that was not unclogged by the water. With a soft, non-abrasive brush and some diluted solution of mild detergent, soap up the area to further ensure that the rim are free of any residue. Rinse with clean water. That is how to remove stains from powder coated wheels.
Making sure your powder coated rims are clean goes a long way in the longevity of the finish, but if you want to go the extra mile, you can also apply powder coat wax polish. After washing, simply wax the rims like you would do your car. After the wax dries, simply wipe it off with a clean rag and your rims will look as good as new. Brands like Meguiar’s offer great top shelf polish, and are recommended for powder coated items.
Powder coat is not an invisible shield that makes metal objects invulnerable to damage. It protects the item from minor scratches and has a great glossy finish. However, like other automotive parts, it needs to be maintained and kept clean to ensure that it does it best, until the time comes that it needs to be replaced. Should you encounter a problem with maintaining your powder coated wheels, bring them over to Wheels Respray and let the professionals do it.
Can you clear coat powder coat?
Powder coating is known to be stronger, durable, and lasts longer than other paint jobs in market, which is why more and more people are choosing to powder coat their metal automotive parts. However, there are questions being raised about how to apply it, such as can you clear coat powder coat, which is understandable, because there are those who unknowingly apply powder coat to materials without properly understanding them.
Powder coat is electrostatically-charged paint so when sprayed on metal, the powder bonds onto the material. Typically, it is applied to metal surfaces. Given that it bonds with the material, the powder coat provides a protective coating that makes the metal surfaces stronger and does not chip easily. however there are those who still doubt the resilience of powder coat, so they always ask can you clear coat over powder coat. Yes, car owners can apply clear coat over powder coat, but it is rarely recommended by panel beaters or car repainters. Clear coat is considered inferior compared to powder coat, and although it will not affect the paint job it is very recommended that powder coated materials are left as is. At the same time, majority of powder coat paints in the market now resemble a clear coat finish after the baking process, so when it’s all done, you will immediately see that you don’t need to clear coat powder coat.
Another thing you might consider when asking repainters if they do clear coat powder coat is for oxidation. Most metals need clear coat to avoid unpainted parts from oxidising, and sometimes even parts with paint are not assured from oxidation. With powder coat, the powder sticks directly onto the metal, so an even coating is always assured even before the curing process. After it bakes, the entire metal object will then be safe from oxidation, therefore there is no need to put clear coat.
Using clear coat on metal objects has been a necessity for the longest time, especially to those who do not have access to powder coat. It offers protection from chipping and oxidation, and gives the metal a glossy finish. Powder coat offers all of those, plus more. With powder coat, the metal is already protected by the paint itself, and has a glossy finish. It is also longer lasting than other paints, so refreshing it will take longer than others. Powder coat gives more value for your money over time, compared to other paint products, which just goes to show why it’s the choice of paint for many.
What Materials Cannot Be Powder Coated?
Powder coating is fast becoming the choice method of applying damage-resistant paint finishes to different products. Powder coating is primarily applied to metal parts, but its effectiveness and overall durability makes people want to put it on different products, thus begging the question: what materials cannot be powder coated?
Primarily, materials that CANNOT HOLD A CHARGE cannot be powder coated. There’s a reason why majority of powder coated products are metal: the paint is ejected from the powder coating gun with electrostatic to make it cling to all nooks and crannies of the metal object so when being cured, the paint melts and covers everything well. You can attempt to pewter coat non-charged items by heating it up first so when the paint lands on its surface it melts immediately, but do note that this opens up opportunity for the paint job to fail, compromising the integrity of product.
FABRIC is another item always brought up if it can be powder coated. Yes, we understand that clothes hold static charges every now and then, but the answer is no, fabric cannot be powdercoated. Yes, the powder paint will probably stick to the fabric, but unfortunately very little fabric can withstand the heat of a powder coating oven, sometimes reaching 400 degrees, like he using polyester powder coating. Sublimation is the best method when it comes to fabric, so it’s better to use that process to get the best look possible.
WOOD Is extremely tricky to powder coat because yes, there are electrostatic wood products like medium-density fibreboard (MDF), but most wood products will not survive the extreme heat of the oven. You can attempt to powder coat wood by using low temperature, but doing so will compromise the quality of the paint.
PLASTIC is another product that will not be able to withstand the heat of a powder coating oven, not to mention the lack of electrostatic charge on the material. Like with wood, you can attempt to powder coat plastic by keeping the curing temperature low, but do not expect the best results after.
Surprisingly, GLASS is a non-charged material but can be hacked for powder coating: simply putting any metal behind the glass is enough to make a stainless steel powder coat colour stick. However, much like the other materials, the glass needs to be able to withstand the intensity of the oven during curing, so not all glass materials can go through this.
We understand that powder coating not only gives off a nice finish but somehow embeds the metal item with superior strength and durability in just one coat, and this is something that most products can use for themselves. Regardless the powder coating colours, wheels, callipers and other metal items found in cars are still the best items to apply powder coating to, and we here at Wheels Respray have honed the art of powder coat application.
Can you DIY powder coating?
Powder coating is fast-becoming a primary option for automotive paint jobs. Since they’re mostly made of metal, it is fairly easy to powder coat car parts and end up with a seamless, professionally-made finish. But that professional paint job does come with a price, so many netizens are asking: can you DIY powder coating?
Gathering the Tools
Technically, it is possible for anyone to start powder coating by themselves. Assembling a complete DIY powder coating kit is key: you will need powder coating gun, sandblasting equipment including a sandblasting cabinet, ultraviolet light or oven for curing, and of course powder coat paint. Other DIY powder coating equipment include respirators so you don’t inhale the powder coat when you start spraying, and high temperature paint that can handle the curing process, and miscellaneous safety and paint gear.
The DIY powder coating Process
The process start with stripping the paint on the object you want to powder coat. Doing this in your backyard or garage can be pretty messy, so it would be better if you did it in a sandblasting cabinet so the sand and the paint will just be collected in one vessel. Clean the surface well to ensure an evenly-coated finish. With the powder coat gun, spray the object with the powder coat paint. The gun “charges” the powder coat, making it stick to metal. The best thing about powder coating is the very small window of ruining the paint job by over or under-spraying the object.
The curing process then begins after spraying, wherein the coat is cured either under heat or ultraviolet light, depending on the type of powder coating used. Though possible, do note that the typical household oven should not be used to cure powder coating because of the emissions the paint will set off, so you might want to get a DIY powder coating oven for this. After a few hours of high-temp baking your newly-painted object should be good as new.
DIY Powder Coating Recommendations
If you’re still asking if you can DIY powder coating at home, the answer is a big yes, but it is not recommended for a DIY weekend project. The overall process can be tedious and can cause problems for you and your neighbours, especially during the sandblasting and the curing process. If you plan to do DIY powder coating for any of your car parts like your rims, we highly recommend getting a professional to do it for you, since not only do they have the proper equipment setup in their shops, but their experience guarantees a smooth finish for every project.

Will paint remover remove powder coat?
Newly-painted rims are a thing of beauty. The gloms and brand-new look will always be a feat for the eyes. However, paint does fade over time, and this is true for powder coated products as well. However, if you’re thinking of doing a weekend DIY on your rims, better take it easy before getting a load of paint remover, because powder coat is trickier than you think.
“Will paint remover remove powder coat?” Unfortunately no, your powder coated item will not be stripped of its paint by applying basic paint remover. When paint stripping powder coating, remember the process of application. The powder was electrostatically sprayed on to metal object and then baked in an oven, making the paint and the metal merge together. There’s a reason why powder coated materials lasts long, and it’s the same reason why paint remover won’t work easily.
Another mistake people make is to try remove powder coat with acetone. Yes, acetone will remove the shiny finish and might fade the paint a little, but more often than not it will not remove the paint fully. Unless you have barrel loads on hand, acetone will only do more harm on the powder coated item than good.
Removing powder coat with heat gun is another option, but it is not recommended. Using a heat gun means burning off the paint of the surface of the metal, then scraping the metal off. This is not recommended because most DIY jobs go too hard on the scraping, leaving permanent marks and scratches on the metal. When applying a new coat of paint, these marks will be visible and can leave an awful overall finish.
