thanks for the replies. I am allergic to auto paint in general, the epoxy I mix and apply with foam brush where I have to and where I will put filler on. I can hardly stand to smell it in a can, dang sure can't spray it!!!! I use the ospho where the metal has pitted, perhaps a self etcher would be just as good, donno!? where I take it to bare metal and no pitted surface rust, I have had my guy shoot self- etch primer.
my poor boy method of body/paint work Is I d a it to bare metal, treat pitted areas with acid, epoxy over those spots then body filler can go directly on epoxy, other wise where self etch primer is used, a sealer goes on that before filler. ido all the patch work, pound out what dingS I can, I have to find someone that will spray it for fair labor costs, NOT what body guys figure paint work at!!!!!!! I have shot sanding primers outside and they even mess me up.
