hey since water hit the market ive try some new producs and for my lower paying jobs i have tried the pro-spray primer EBA-50 and the issue ive come up with is that the water paint has not aheared in some spots where the pannel has been hit by either rocks or another car hitting the pannel after the paint job is done. the primer remains in the car but the paint and clear are easily peel off like if they were stickers. im letting everything dry like its supposed to and this only happens with water borne paint but not with solvent. any one has run in to this issue that can tell me how to fix this. this is driving me nuts or at least let me know what other low price primer to use my customers are paying out of pocket and they are paying about $150 to do a fender fix so im really going cheap to help the comunity. please advice
What are you topcoating the primer with, solvent or waterbased paint?
if its peeling off it probably means that its not ment to be topcoated directly without sanding.
im top coating it with waterborne paint and im sanding the primer with 400 grit sand paper :S any more ideas
what brand of basecoat are you using? Have you tried sealing before you base? Waterborne base is tougher than solvent but without the solvent in it there is has no bite into the primer. Strictly mechanical adhesion. Good thing is it won’t lift even during a repaint.
How are you wiping your panels down? What products? Are you making sure you are wiping it till they are dry and not leaving any residue behind? WB requires that you have a very clean surface to start with. I always clean with a waterborne cleaner and a solvent w&g remover before the car is sanded, after it’s sanded with just the waterborne, and in the booth again with both cleaners.
What line of paint are you using too? Just curious if the necessary activators are being used. I’m not an expert on WB but I beleive some lines the hardeners aren’t optional like solvent lines so I thought I’d toss it out there.
