I have the chrome package on my truck and I have done a lot of work trying to reclaim my chrome wheels.
The Chrome wheels were a DEALER option. My truck has chrome exterior mirrors, chrome door handles, chrome damage multiplier, and chrome wheels.
Unfortunately, living in the Midwest, the salt has killed the chrome on the wheels and they are peeling BAD! I now have one wheel (spare) that is losing air because the chrome is peeling under the bead of the tire.
I wanted to get them re-chromed, but the chromers will NOT de-chrrome and re-chrome MY aluminum wheels because they are too pitted since mine are already peeling.
They WILL chrome a set of clean, blasted wheels if you want a set of chrome factory wheels.
I happen to have connections at a chrome shop and I COULD get them to de-chrome them in the same process as it takes to chrome them (they reverse the polarity), however, mine are so pitted that the surface will show through anyway.
I have decided to buy another set of wheels, have them bead blasted, and I will polish them to "chrome" look like what big trucks do. I have a set of LX wheels in my garage that are already blasted and awaiting some trim paint and polishing.
Sandblasting will eat the aluminum too much because the chrome is MUCH harder than the aluminum.
Just chuck the old chrome ones and find a new set to do with what you want.
