I always took the advice of the chief painter in all the shops I worked in and they were all older than me and now as Charlie said they took the lead out and that changed everything.Thanks you guys, I can see I wont be buying any more metal etch. I have never used metal etch primer, it has always been a clear to yellow PPG product they have sold me to wipe or spray on and wipe off. Probably just because they smelled a novice.
Etch primer is better than putting primer on bare metal for sure. Charlie helped me do the right thing on using epoxy or mine would have been done in etch primer because that's what I was told to do years ago.
Your Fish paint job looks great in the pictures are you needing to take it down to metal?
