I've recently brought some MV3 wheels refurbed in black.

I had my car washed and the wheels seem to have lost their shine??

would should be used to clean powder coated wheels?

I'm guessing I'm going to have to get a full refurbed done also..

are these mobile refurb guys any good?

look for wheel protector spray (walmart or pepboys) for $8-9.
I spray it after wheels are cleaned, this repels mud/brake dust and keeps wheel shining.

I had some powder coated wheels ruined by the dealership because they didn't know the wheels were PC and they used aluminum brightener. It bleached the wheels. They paid to have them redone.
