I used dx579 and 520 and leaves white coating and a Lil surface rust on panels. Rust puts turned black?. Going to let dry sand down and apply waterborne w&g and epoxy. Should this be good enough?
I used the klean and strip phosphate and a red scuff pad and the black pits are going away. I'll do that one more time then rinse off let dry and 80 grit and w&g then epoxy. That ppg stuff I couldn't seem to get it right.
