Powder-coating over chrome?
ok so i finally found a powder-coating station here in the valley, its about 1 hour away from where i live. i talked to the guy and hes gonna charge me $300 for all 4 wheels. i think thats a good price. my question is, will i have to worry about them spraying over the chrome? he said that if my chrome was already chipping (which it is) and if it would chip more it would come right off along with the powdercoat. also that if i had bubbles already on the chrome {which i do, pitting) thats a sign of weak metal under the chrome so sandblasting b4 would make a big hole. what should i do? should i sand blast them anyways? or just powder-coat over them?

definitely blast them, if you dont you'll regret it. if the chrome is getting bad already and blemished, its just gonna get worse and you'll be pissed the first time a huge chunk flakes off at the car wash. going with a gloss black or a cast iron-ish color?

Pitting is not, necessarily a sign of weak metal. However, if your chrome is pitting and flaking....have them blasted. If the guy refused to blast them, have them chemical stripped. There will, more than likely, be pits in the metal. Powdercoat will NOT fill those in. However, there is a putty, similar to bondo that a lot of powdercoater's use to fill in these gaps. The proper way to do this is to repeatedly dip the wheel in copper solution and then sand...and repeat over and over again to fill in the pits.
Depending on how badly your wheels are pitted or flaked, it might be better to just sand them down and have them professionally painted.

they are not pitting REALLY BAD. just a little on the edges. im gonna call a local sandblasting shop to see how much this is gonna cost me. so far its still better than buying new wheels.

About thirty years ago I had a similar problem with some ET mags. They were a two piece wheel with the rims being steel and the centers being cast aluminium. The centers flaked and the rims pitted and rusted (driving in salty beach sand is hard on wheels). I had them bead blasted, then hit them with Rustoleum primer and top coat. No problems for the next five or six years when I got rid of the truck. They didn't look bad at all.
All that being said, I wouldn't spend lots of money powder coating already compromised wheels. You can't make a silk purse out of a sow's ear. At least thats what my Grandma told me.

I'm not an expert either but I will give you my opinion anyway, if the base (chrome) is already chipping that would not seem like the ideal surface for paint to adhere to.
