I painted these with dupli color performance wheel coating-
Here is what I did-
washed throughly with soap and water
Sanded with 400 grit sandpaper
used a duplicolor prep wipe
3 layers of black
3 layers of clear
I would say it looks about 7/10. There are a few spots where the paint didn't like the rim or I put it on too heavy or something. They are not bad and only noticable to touch.
The most important part is to sand alot! I spent 2 hours sanding and I wished I had spent more time on it.
As for clear coat- The black dries to a satin finish. So the clear coat gives it a gloss finish.
I can tell it's not perfect, if you have access to a spray gun and have the skill, I would suggest using it instead.
