Need 4 chrome wheels stripped and powder coated
RFQ: I operate a small-scale specialty auto repair shop in Northern NJ with a customer's car having aluminum "simulated 3-piece" wheels with chrome peeling.
The owner expressed interest in having the chrome stripped to a point where the wheels could be refinished in a matte black or anthracite powder coat.
From the posts on this board, I assume the chrome can be removed with muriatic acid without much problem, but would that alone be enough to prepare for powder coating?
The vehicle is not a show car, and some minor cosmetic defects in the recessed areas etc would be acceptable if the durability of the powder coating is not compromised.

Ed. note: As always, gentle readers: technical replies in public and commercial replies in private please (huh? why?)
A. Hi Tom. "Chrome" wheels actually have a fairly heavy plating of nickel followed by a very thin plating of chrome. Although HCl will remove chrome it won't remove nickel and, since the nickel is peeling, it must be removed.
The chrome should be stripped, the nickel stripped, and the wheels prepared for powder coating by chromate conversion coating. Luck & Regards,
