I have painted my tank about six times!!!!! I apply a two part color, silver base then a red (candy) topcoat. Followed by two coats of clear. I use the best quality rattle can I can find. Like with most things I try, I end up redoing it so many times by the time I'm done I have it mastered. My problem is with my gas cap and rough terrain. Gas leaks out of the cap. I've tried to use two rubber gaskets (no help). Anyways!! Is there a product or way that I can use to protect my paint from the gas leaking?
