Won't polishing the rims take off the clear coat?
Nothing can be further from the truth. If a person could sit down and take a minute or two with some measly polishing paste and end up being sucessfull in removing the clear coat on a coated set of alloy wheels, then that coating would be useless. Those Urethane coatings are seriously stronger than the majority of people think. You can rub 'till your hearts content and, you may, I mean MAY, after about an hour, in the same exact spot, dull that coating, just a tiny bit.
So many on here and other RV forums think that if you get anywhere near the clear coat with polish, YOU'VE RUINED THE WHEELS. I laugh when I read that, over and over again.
It's simple, first, Accuride, the brand of alloy wheels that are installed on a zillion coaches out there, have a few different finishes on their wheels. Here's an exert from their website:
All Accu-Lite Aluminum Wheels are available with Standard Polish (SP), Extra Polish (XP) and Extra Polish with Accu-Shield (XPC).
The last part of that statement, "Accu-Shield" is the name of the coating on their wheels. They take serious pride in that coating.
Anyway, if you take a tad bit of rubbing/polishing compound and put it on a small piece of say, micro-fiber cloth, then rub on a spot on any of your wheels, and, within say, 5 seconds or so, look at the cloth. If it's black in that short amount of time, your wheels are UNCOATED.
If it's not black, or showing any signs of being black, your wheels are coated.
