It's a known fact that a set of wheels can make or break a car. We've seen some of the biggest "junkers" become legendary with a nice set of wheels and a ride height adjustment. The opposite can happen when you have a nicely restored vehicle that has dirty, beat-up, or badly finished wheels. It can ruin the overall appearance of the car or truck. We're here to show you how to make your rolling stock look as good as your ride with these 10 tips to powder coated wheel perfection.
1. Preparation Is Key!- Powder Coating, like traditional paint, requires a clean, dry surface for the best results. We suggest to media blast your wheels down to bare metal for the best powder adhesion. Powder coating is a "high-build" coating that will fill the texture left by media blasting. Eastwood offers DIY Media Blasting Kits that make it a pretty affordable option. The other option is to remove the finish chemically or mechanically. Both methods can be quite messy and time consuming, but they do the job. Once the wheels are free of any old coatings, wash them down with a solvent like PRE or After Blast to remove any grease, dirt, or grime. At this point we'd suggest wearing clean rubber gloves. The oil from your skin can transfer to the surface and actually cause imperfections in the powder during curing. Remember, the cleaner the better!
2. Pre-Bake Wheels- The wheels on your vehicle are subjected to some of the harshest conditions on your vehicle. They see extreme temps, brake dust, grease, grime, salt, and anything in between. No matter how often you cleaned the wheels (especially cast wheels), they'll still have some residue or contaminants baked into the metal. Those contaminants can release when the wheel is heated up. If that happens when baking and curing your powder, it could cause popping, bubbling, or even a fisheye effect in your cured powder. We suggest to bake your wheels at 350-400 degrees for 30 minutes to an hour to assure that you have released and baked out the years of contaminants in the metal. This way when you apply the powder and cure it at a similar temperature, those contaminants would have already been released.
3. Assure you have a good ground connection- Grounding your wheels to the powder coating gun is very important. Most wheels have some tight corners and crevices that can be difficult to get the powder into. The static charge that is created by grounding the wheels and charging the powder is what helps the powder cling into every crevice. Without a good ground the powder won't stick in these spots and you'll get an uneven finish. We've had luck by running thin metal wire around or through each wheel and then connecting the ground to the metal rack the wheels sit on for coating and curing. This allows you an easy spot to clamp your ground clamp to the rack or even the wire under the rack.
4. Hot-Flock you wheels- "Hot-Flocking' is a procedure where you preheat the part and immediately coat the wheel. The hot wheel will help the powder "stick" to the surface easier as the powder may begin to melt as soon as it hits the surface. This technique takes some practice to perfect. You will need to be quick with laying the powder down so the part doesn't cool too much. Also be mindful to avoid laying too much powder during this method as you can get "runs" or "clumps" of powder that will collect in one spot.
5. Use High Temperature Masking Tape- Use this high temp tape to mask off lug holes, hub bores, and any other areas that have a tight tolerance and could cause issues when refitting the wheels. You can also use this tape to mask off portions of the wheels to apply a second coat of powder for a custom application.
6. Apply Clear Coat Powder- Use your choice of clear powder to add an extra layer of protection to your wheels and make cleaning brake dust and road grime off easier (high metallic and textured powders especially hold dirt and grime!). Additionally our high gloss clear powders really give your finish a "deep" "wet" look.
7. Protect the inside of the wheels- One of the nice things about powder coating is that it helps seals the metal and keep your wheels from corroding. We have found a good practice while powder coating your wheels is to apply a layer of powder on the inside barrels of the wheels to protect them from corrosion. The inner barrels or hoop see the harshest conditions. You can make the coating as basic as satin black powder or go full custom and use an eye catching Translucent or Candy Powder.
8.Remove anything that shouldn't be coated- If you don't want it coated or it can't handle the heat, you must remove it before starting the process. This includes valve stems, sealing rings, trim pieces, lug covers, hubcaps or center caps, etc.
9. Use metal or high temperature filler on damaged wheels- Have a wheel with some "curbing" or damage? Use an all metal filler like Lab-Metal to fill and sand imperfections smooth. Powder Coating can have some filling properties, but heavy scratches or gouges need to be filled. Alternatively you could use an AC/DC Tig Welder to weld and fill major damage.
10. Use a Quality Powder Gun- As mentioned earlier, powder coating wheels can be difficult with all of the crevices and tight areas you need to coat. Not all powder coating guns are created equal and you need to make sure you use a gun that has the ability to switch to a lower voltage that allows the powder to cling to those hard to reach areas. Our Dual Voltage Powder Coating Gun is one example of an adjustable voltage gun.
If you follow these tips and take your time, you can make your wheels look as good as the rest of your ride and last just as long too!
Here at Eastwood we have a love for anything with wheels. One of our product engineers, Evan, is a big time ATV enthusiast. He took this past weekend to give his quad a new look by blasting and powder coating the chassis and associated parts. He used the Eastwood Dual Voltage Powder Coating Gun, and a combination of HotCoat Metallic Blue Powder, HotCoat Black Stardust Powder, and HotCoat Reflective Chrome Powder to coat his quad parts. Evan wanted a tough coating that would continue to look good even after a day out at the trails and he knew HotCoat powders would be up to the task!

I'm building a few projects at once, and it seems just about every one of them needed some sort of black powder coating done before I could start reassembly. I took this past weekend and cranked up my favorite Rolling Stones song and tackled my growing pile of parts for black powder treatment.
There were 2 steps to this process. The first was cleaning the parts with the media blaster. Since I had some large parts that wouldn't fit in the blasting cabinet, I decided to use a mix of soda blast media and aluminum oxide in the dual blaster to quickly remove the years of paint, rust, and grime on these parts.
An important tip is to sift your media through a strainer before it goes into the blaster. This is your last chance to make sure that there aren't any pieces of oversized media that weren't broken down enough. The smallest rogue piece could clog the blaster and cause headaches! This is extremely important if the media isn't high quality or has been stored in a questionable area where condensation could have gotten to the media. Either way it's a good habit to form. Sometimes you'd be surprised at what you catch!
Once I blasted all of the parts I treated them with Eastwood After Blast to give them one final cleaning process and optimum powder adherence.
The fun part of this process was finally here, and I started by grabbing my Dual Voltage HotCoat Gun and doing a layer of high gloss black powder followed by hot flocking a layer of ultra gloss clear powder over the parts. This combo is one of my favorites. It really gives an ultra-deep, shiny look to the black that is hard to beat!
Once that batch had cured I moved on to do some engine brackets and other items in black wrinkle. This powder leaves a nice O.E. looking finish that is subtle, yet still clean.
After all of this, I can say I am excited to bolt these freshly coated parts onto each car, I just need to find the time! We want to see what you are powder coating, feel free to share your photos on the Eastwood Powder Coating Forum!
Media blasting is a job that can be quite messy and expensive. Most blasting systems are great if you plan to use it often, but the cost definitely can be overwhelming if you only use it once or twice. Normally you would need a cabinet or a stand-up pressure blaster that requires a large compressor, an efficient air drying system, and loads of media; even if you are just doing a couple small items like valve covers, intake manifolds, etc.
Here at Eastwood we recently released a kit that will allow you to get blasting quicker than ever before. With our new Small Job Media Blasting Kits you can be up and running in no time without the need to invest in a large media blaster or cabinet. If you want to strip and recoat your old parts we suggest coupling the new small job blasting kit with one of our HotCoat Powder Coating Kits. Using the two kits together will get you restoring and coating parts quicker, and more affordably then ever!
As always keep your suggestions coming with your ideas for new products to help you do the job right!
