this is copy and paste since you need to be a member to view.
Materials needed:
* 1 - 2 cans of Primer (preferabley a white color, see below)
* 1 - 4 cans of Paint (depending on how many coats. For reference I used a 12oz can to coat the stock Spec wheels 2 times. THe type of paint I used is calls "Dupli-Color High performance wheel coating")
* Clear coat. ( I suggest duplicolor high performance clear coat for wheels. Like the wheel coating, its made for coating wheels)
* 150 grit Sand paper
* 800 grit sand paper
* 2000grit automotive sand paper
* Soap and water
1. Wash off the wheels then sand the wheels down to the metal or just scuff the surface up really really well.
2. After sanding properly clean off all dirt and what not thats left over with soap and water. DRY THOUROGHLY!
3. Mask off anything that you don't want painted, i.e. the tires and what ever you want to add as a pattern.
4. I used 2 coats of primer. Now my friend didn't use primer when he coated his rims, but I suggest it. Its there so the paint can stick to it. A good tip is to buy a white colored primer since grey won't work as well because the wheels are going to be sanded down to the metal.
5. Use 2-5 coats of paint. Add more if needed to make a deep rich color. Let the paint settle about an hour to 2 hours between each coat. Wet sand with sand paper(800 grit) after each coat of paint. Dry thouroghly.
6. Put on at least 2 coats of clear coat. Thats just there to protect the rims. Again like the paint, let each coat set at least an hour to 2 hours. Wet sand after each coat, but do not wet sand the last coat. again, dry thoughoughly.
7. Wait overnight before putting the rims back on. This will give the paint and everything a chance to settle.
8. You can go ahead and wet sand with the 2000 grit after you let everything dry off. after the wet sanding wax the wheels to get rid of the hazing. this will give the wheels a nice shine and cleaner look.
More tips:
Depending on where you live, do not paint at night. In my area it gets really cool and damp. Temperatures like that won't allow the paint to stick very well. Paint in temperatures above 60* and with low humidity Exclamation . If possible let the rims dry and cure in the hot sun.
