I've owned my e92 msport now for few months but notice that the high gloss shadowline trim around the windows has taken on a tarnished look and is really quite noticeable. It nearly looks marble-y with a bluey hue. Cleaning it when I'm doing rest of car makes no diff. What do I do? Is there something I can polish it with? Thanks guys!

Use a cleaner polish on it. What products do you own? I had shadowline tirm on my X5 and I treated it like the rest of the car.

Might want to give Mothers "Back to Black" a shot...pretty easy to source locally

I've found that it works much better than sealants for black trim, especially really old, oxidized trim.

He has shadowline trim which is not a hard plastic, but rather painted and cleared. Using back to black would result in a smeary look with no result.

I didn't realize that... if the shadowline trim is painted, definitely don't use the back to black. Sounds like it's time for a fine polish applied with a PC or rotary.
