Rust resistance coatings
 

Hi all,

Got some rear brake stuff to replace and a front sub-frame.

Factory just gave a quick coat of black point. Was this epoxy?

What do you think will be best for rear backplates? Epoxy or powder coating? Or even enamel paint (Rustoleum).

Do you know if powder coating will adhere to epoxy paint? I know there is a system of zinc base coat (don't know if that is heat cured) with powder coating over that.

Problem with powder coatings is that once breached it acts like the early bitumen based floor pan coating of the 60's to 80's in that water ingress made matters worse but it was not obvious until latter rust stage.

All experiences/knowledge welcome.
