I have a vehicle with por 15 on the chassis and suspension and want to cover it with eastwood 2k ceramicchassis black. Por 15 can be painted over but must be cleaned with marine clean and then etch primed as the etch primer will bite into the por 15. Eastwood says to put epoxy primer down for its chassis paint.Will the etch primer under eastwoods paint still give as durable a finish as would the epoxy primer?
