I actually used an automatic car wash this past weekend and i find that i notice the discoloration more...

Just went to the store on lunch and couldn't find the Ultra cut.... But there was a meguiars ultimate compound. It's a little less agressive than the ultra cut.
Anyone know if it'll do the same thing?
As for the wax i bought Meguiar's Gold class... hope that does the trick!

Don't remember but you can go to Meguiars website to check for rate of cut (they go from 1-10, and 10 being the most agressive and M105 is 10).
I got mine from a shop which sells auto-paint stuff, not local auto parts.

IMHO, as long you are willing to just work it a few times any compound will work eventually, the unique thing about M105 is that it uses chemmecial reaction to soften the paint and let the agitaion from polisher/machine to do it's job faster (The idea must come from black-smith which heat the metal to soften it before tempering/forming)

The only way (once you've polished) to keep it from happening again is to keep the trim waxed. Collinite 845 is fantastic as it's easy to apply and lasts a long time. Not to mention, just a little goes a long way.

I actually noticed that on mine too recently. I used piece of cloth and kept rubbing, it started to go away. I am not sure exactly what caused that thing. Usually oil causes those kinds of discolorations.

I guess nobody check the articles sections above :P

It's anodized aluminum...it's oxidation.

Used Meguiar's ultimate compound and it worked like a charm!!
Then i slapped on some Meguiar's gold class liquid wax to shine that baby up!!

Great! Glad it worked out!
