Lol.. I have the exact same sheet, with the exact same issue.. Doing a complete restore. So just don't have the extra cash to powder coat at this time.. Basically just painting to keep parts from rusting. I'll powder after build is done and I get a few rides on it. Your paint hid is only as good as the prep work underneath it. What brand of paint are you using.. IMO.. Rustoleum is the absolute WORST to use. Just make sure to remove all old paint and rust. Sand with 120 grit paper.. Then MOST importantly..clean surface.. I use 50 to 70 % rubbing alcohol. Cause it's cheap, drugs quick and works good. DO NOT use 90%. It leaves an oily film and paint comes right off. After cleaning, DO NOT touch parts with bare skin... Now prime.. Once dry...sand primer with 180 grit paper.. Clean again and paint..that's all there is to it. Unless you want a very shiny coat.. In that case, you would want to lightly scuff the paint with RED scotch bright, clean again and then clear coat....I had to repaint all of my parts 3 to 4 time till I got all of my mistakes worked out .... I tried a couple different ways, but finally got advice from my brother-in-Law.... Which has been painting cars for many years. Good Luck.
