my dad and i just repaired and painted my 76 targa
quite a bit of repair work done carrera flares welded in, acrylic primed and spray puttied then 8 coats of gp white in acrylic.
also painted the calipers using acrylic primer and slow dry enamel, then the paint basicaly fell off, (the calipers)spoke to the paint shop they said i should have etch primed the cailpers first.
ok no problem cleaned the caliper back and etched pimed ready for a coat of colour.
what is worring me now is, if i should have used etch primer on the body due to the galvanise, much of the body was either sanded back to metal or left with only a dull looking galvinised coating.
there are no sighs of an issue at this stage, but havent bolted doors or fenders back on yet
