Finally got my grille back from the chrome shop. I'm attempting to repaint the sections of the grille that are silver argent/black. Started with the black, but most of the paint peels off along with the painter's tape! Does anyone have any recommendations for a primer to use on chrome? I'd rather not scuff up the chrome that's going to be painted over, because I want the painted areas to be smooth. Ideas? Suggestions?

When I did that, I used gorilla tape to mask off the chrome ridges that matter, then I scuffed the heck out of everything else. Even ran a dremel inside the grille to smooth out the pits that were on the painted surface. After that, I used an epoxy primer followed by Trim Black Matte. That was a couple years ago and it is sitting real pretty in a box on a shelf.
Next best would be 180 grit paper followed by bulldog then self etch primer if your going g the spray bomb route
My '64 Riv. had the air intake grills that were painted with some chrome edges. When I soaked the grilles to take off the paint it was a yellow color. I know it took 3 days soaking in the old style smelly carb. cleaner to remove it. Then I had to do more hand work to get off the rest. Tom T.
x2 on what may have been the job back in the day. Because Cr plate is so smooth, a little bit of scuffing is the only way to gain some paint adhesion for a top coat to last. The kicker is, you might be surprised how well that topcoat will do without a primer AFTER the scuff. And sorry, I can only speak for my painting over Hexavalent Cr which is what our old stuff has. Regarding Trivalent Cr3+ I haven't tried to paint over that. For all interested, Hex is doom for health on the mfg side and downstream too, and largely phased out. Tri is bright and pretty, durability is lesser. Devon
