Thanks guys. If i do use brightside, and god forbid I am not able to level it out, I assume I'd have to go to the extent of sanding down my whole car down to metal. To do this, I was thinking of using a orbital sander with an 80 grit disk. Then once that is done (is 80 grit okay?) Now i know before I prime the metal has to be sanded but wouldnt it already be sanded with the 80 grit disk or do I need to sand again? And then I would prime, and then etc. A friend of mine showed me the idea as atelast 60% of my car is bare metal :/. And when I do prime, do I only need one coat since the tremclad has its own primer in it anwaysor would I need more than once coat of primer?
