you would sand it down to bare metal then a coat of self etching primer then 1 coat of rustoleum then wetsand real good, the another coat and wet sand again then another coat and again wet sand. i went to a state wide car show when the winner of the best in show trophy came up to the stand he proclaimed it was a wet sand rustoleum job and he left.
if you take the time and sand real good the rustoleum will last forever and look amazing its a self leveling paint so it can shine like a new penny.
All that work to save $150. Not worth it. Rustoleum is THE worst product on the market. I would never recommend it for anything, especially automotive.
You can't tell me all those rollers, sand paper, sanding blocks, primer ect only added up to $50.
