I've got two chrome bumpers that I want to paint car color. Is simply roughsanding and etching them sufficient to provide good bite or is there another trick to doing this? I read somewhere about a process of dechroming, where you reverse the polarity of the dip and the chrome falls off. Sounds like cowtipping to me, but then, what do I know? Anybody?

It won't stick.
Sandblasting will anneal the chrome and it will peel off, but I've never done something as big as a bumper. (I don't know if anneal is the proper term, shot peen maybe?) |

Tom It is not cow tipping. The chrome does not fall off but it will come off and chrome plates a different object in the tank. Then the copper will come off the same way. This is what they do to de chrome wheels. Wheels cost $20. Each. Bumpers may be the same. Bob B |

There are adhesion promotors made so you can paint the chrome bumper. I had a set of chromed 2L Fuchs and had the spaces between the paddles painted black. Duplicolor make adhesion promotors last time I looked.

Duplicolor make adhesion promotors last time I looked. You are talking about two different animals wheels are aluminum bumpers are chrome. You don't paint chrome. Shake lose with the dollars and do it right or don't do it at all. Bill |

I used my angle grinder with 320 sanding discs and went over the entire surface to rough it up. It didn't take that long. I sprayed truck bed liner ( Dupli-color ) and it's been holding fine for 6 months now.

Most 914-ers want chrome. Usually an easy trade if your chrome is decent. |

Tom What are the bumpers condition. Maybe someone is willing to trade. The rear bumper is in pretty good shape, not concours, but a good DD. Front has a bit of rust around one foglight opening, probably a low grade DD. I thought about a trade but by the time I pay shipping I figured I might as well pay for the dechroming. Anybody close by need a chrome bumper? Tom |

I just paid good bucks across several years to be cheap (I think ~$400) to get decent set of chrome
Someone will trade for sure I'll have a set of black, but not till over winter when I get these chrome ones on (IMG:style_emoticons/default/idea.gif) |
