  • Painting over pitted chrome

    I'm wimping out on my 55 President, gonna paint the grill body color. ($$$$$) I've sanded the "pits" down smooth, can fill them with primer or body putty, but feel there should be something in the pits to stop corrosion. Shellac, POR? what do the pros use?

    The pros I have seen paint pot-metal trim removed the chrome, sometimes by sandblasting, and then filled and smoothed it just like sheetmetal.

      I painted some really horrible pot metal pretty much the way you describe. Sand, body filler, sand, prime and paint. Came out real nice and still fine after 2 years.

        It won't corrode at all if it is well sealed up. you only have to worry if there are holes all the way through. Of more concern would be roughing up the plating enough for the paint not to peel off.

          I'm knocking off the roughness (and the smoothness of the chrome) with a 90 deg. grinder and a 80 grit sanding disc. It seems to work well, taking off the high spots and just buffing the good surface. I started on a really bad turn signal housing, about half of the surface is pits. I wondered if I should clean out the pits with a pinpoint air grinder, or just fill them with filler. I am going to have to do the inside corners with a die grinder, the 4 1/2 disc won't fit there.

            Yes, Tom- be sure to clean out any pits, like cleaning out a cavity in a tooth; just grind or drill it out. Also be sure to get all the chrome off. I recommend epoxy primer over the bare surface before anything else, then fill and finish as any other metal. Should last a long time after that.

              Get ALL the chrome off? Holy Cow, Have you looked lately at a 55 grill? If the chrome is sound (between the pits) can't I just scuff it so primer will bond?

                I would think so, Tom. Studebaker even painted chrome on some low trim cars, and it held up 50 years.

                  Scuff the chrome really good and use a metal etching primer.

                      all of the advice or just the results? If I could, I'd be helping you - you know I've got ideas of just how that grille should look!

                        I guess I should clarify what I'm thinking[:I]

                        It's not necessary to get ALL the chrome off... I was just thinking about any peeling, blistered, or corroded areas, including those little pimples that develop. Any solid, unaffected areas can just be roughed up thoroughly and primed over.

                        It is critical to get any corrosion completely out, or it WILL pop through fairly quickly.

                          Before you prime, go to your local car paint store and by a rattle can

                            Thanks, Dick, I'd not heard of it before, and Bob, that's what I thought. I don't have any blistering, just pits.

                            George, your ideas are welcome. Results will be shown.

                              I have used epoxy from Home Depot. It's the stinky kind that comes in a double syringe. It doesn't take much material to fill those pits, so I would use something better than bondo.
