So I just put new 17" TT2s on my RS, and when they were putting the tires on the rims they got some of that liquid they use to mount the tires on a couple of the rim edges. Of course, with them being polished, these spots are clean but now the rim is whitish in those spots...

These are my first polished rims...what is the best thing to use on them? Chrome polish? Never Dull? Then wax? Thanks for any responses...

 

I would try Mother's Mag & Aluminum polish first.

 

With one of these:

 

I have a set of TT 2's on my T/A.
Heres how I keep them up.
First off. The powerball mini works great I've found that blue magic makes a metal polish that works better than mothers. It seems like you can get it to shine quicker and the blue magic leaves a coating that makes it take longer before the wheels start to oxidize and need polishing.
When I wash my car and it comes time to do the wheels. I use mequires hot wheels wheel cleaner. You just spray on and wait a few seconds and wipe off.
Then they look as good as they were when they were freshly polished.
I wash my car once a week but with using the blue magic polish and mequires hot wheels I only need to use the powerball mini 2-3 times a year
