How can I de-chrome my grill

my grill only has 1/2 the chrome left on it, and I'd rather paint it the body color instead. Can I de-chrome it myself, or is there a primer I can use over chrome.

If I have to take it in is there any type of shop that specializes in this.

Thanks

28 Essex,
If the chrome is not peeling, or stripped off, in spots...
You can give it a light sand blasting, apply a sealer, and paint the body color of choice.

Oh I'm sorry I should have said, it's flacking off in places
I haven't tried blasting it yet, does the sandblaster sometimes peal the old chrome off?
A friend of mine tried sandblasting newer chrome, and I'm not sure if he used the wrong primer, but the paint didn't stick

Essex,

My experience has been...If the chrome has peeled or flaked.
sandblasting very close, gets rid of the problematic areas. I have always tryed to get the chome stripped, to the point were I can see good adhesion. The uneven areas can be treated like any other body panel. (IE: filler,poly,etc)

Essex,

If you can't get the sandblasting to do a good enough job, on the edges, use a 36 grit and then an 80 grit on a grinder or d/a.

You are going to want to use a good etch or epoxy primer to stick to it. Just any old primer or sealer isn't going to do.

I've sandblasted an almost new chrome bumper, sprayed with epoxy primer (PPG DPLF) and topcoated with good luck. It's on a big 4X4 and has gotten a couple of dents in it without disasterous results. I believe the secret is that you want the entire surface dull, no shine left anywhere. That gives the paint enpogh little pits that it sticks well.

Find a pace that chromes and they can strip it clean. Under the chrome you have copper and nickel and rust. That is why the chrome is coming off. The rust or contaminated areas are letting everything else come loose.

painted over chromed parts

Like Kevin said take to chrome shop to have it the chrome stripped off. Then have the surface LIGHTLY sandblasted to etch the surface. To prime the part, use the YELLOW primer thats used for aluminum and non steel. Its an special etching primer, you can buy in a spray bomb. Then prime and prepare over it with regular lacquer or high build primers.
