Re: thinking of powder coating my ccw sp600's they can't stay clean and scratch easil
I got CCW's and chromed them. It works great and looks good too. The biggest thing you can do though, is get some ceramic pads like someone already mentioned. I have just normal, run of the mill, ceramic pads on my car and I have BARELY any brake dust even after driving on road trips. I know they have the green and red pads, but IMHO I don't think they are good for anything except costing more than the ones I got.
Don't bail out yet on your polished rims. Get the ceramic pads first. The best thing for polished rims, that I have found, is a good spray down with a nozzle, then I washed mine with the same soap I used to wash my car, Meguires Gold Class. Keep up on them! If you drive your Viper a lot, then wash the rims at least 2 times a week. If it is a weekend car, wash them after your weekend driving is complete.
Finally, go out and buy yourself a gas powered leaf blower. Pretty much anything will scratch a polished rim. The leaf blower is great for drying your car and your rims because you will have no streak marks, no water spots, and most importantly, no scratches on your rims! Hope this helps. Good luck.
