I just picked up a set of PIAA Super Rozzas in Hyperblack (19x9, 19x10) from another member on the forum. I have never bought a set of aftermarket rims before, but I really like them - like a makeover for my car (BS 2003.5 coupe). Does anyone have some tips on keeping them clean? Particularly the lip and the (many) rivets? Any feedback from those who have had the lips repolished?

Thanks a lot
