Protection for fully polished wheels

That's what I figured since they won't see much grime, but just wanted to make sure the stuff would be safe, never dealt with fully polished wheels, just painted/cleared

 

When it comes to a wheel sealant, there are a lot of choices you can use...You can try one of your favorite paint sealants, just don't use carnauba wax, as wheels get pretty hot and carnauba wax will just melt...
I really like Cquartz on wheels, as well as Wolf Rim Sealant...
