| Post subject: | Painting over chrome |
I have a tappet cover that is chrome but has lost a large amount of the chrome and has surface rust all over it. I am thinking of painting over it with the same colour that the rest of the engine will be painted in. Can i paint over the chrome? i am assuming i can sand it, undercoat it and then paint over it. |

Sand blast it first or the paint won't stick. |

Never done it before, but I guess (and only a guess  ) that like all other substrates, it needs to be keyed in. As the doc sujested, maybe sandblasting to remove it alltogether, being heavy handed with a wire wheel?
Maybe pop a phonecall to a chroming facility. Hope this helps. |

had a go today at sandblasting the chrome off the tappet cover. didnt really work. it seems to help remove some of the rust that has taken hold but didnt really do much to the chrome. does anyone know of another way to remove the chrome off the tappet cover? i really want to reuse this tappet cover because it has the breather on the top and i like this particular one. maybe acid dipping would remove the chrome? |

The proper way to get chrome off is to take it to a plater and have them strip it, its basically the reverse of plating it. Normally you don't sandblast it off, you just roughen it up and try to get the paint to stick to it. Tim |

What media were you using in your sandblaster jester? As matt said there are a multitude of different media, some harsher than others. A wire wheel should work. I would be worried about just keying it and painting it. Reason being that you said that it was rusting through the chrome, so the parent material was already oxidising when it was chromed and wasn't cleaned properly by the platers. In short without the jibber jabber, if you key it and paint it, it won't last long before it starts bubbling off. There are some products available off the shelf at paint shops that under normal circumstances where the chrome is in good nick, will act as a tie coat or sealer for the chrome, you apply it and paint over it. I can't remember what they are called, I've never used them. And to behonest I I know nearly nothing about how they work or anything. . . . Wire wheel, smooth with 240 and paint away. |

Cheers That sucks, back to trawling through your old advice. It was nice to have a pro spray painter on here that explained the reactions behind the products. Not just use this, this then that and wipe with that. |
