I just received my brand new Matte black 3 piece wheels (powder coat). gloss inner and outer barrels and matte black center spokes. The first thing I did before install was clean them and put on 2 coats of CG Jetseal. After the first wash I dried them and there is a white residue on the matte black portion. How do i get this off and what is the best way to prevent it in the future? I am sure I could use some QD to shine them, but that I think will just mask the problem until next time. Any recommendations?
