Here was my process:
Sand. I believe I used a 400 just to get the gloss out then washed and cleaned it with a prep
Used a Index card trick so I dont spray the tires:
Then used very light coats spraying as evenly as possible in long strokes. Primer first then paint then clear. I think I used 1 can of each step from Autozone. Maybe 2 greens cant remember.
