Do 3M products hurt black rubber/plastic?

So, do products like 3M SMR or FI-II stain rubber seals or black plastic parts?



If so, I guess I can tape it off before I go over the car with my PC?



Also, how would I remove stains? Would 303 Protectant remove it?



Thanks in advance.
 
On a side note, I always tape off my rubber trim with 3M tape. I have very little of it so it's quick. It allows me to cut right to the edge (and overlap on to the tape) where the rubber meets the paint with a tight perfect coat of polish / wax. I peel off when done and glide on "Black Again." Perfecto!
 
I have an older car, where the plastic/vinyl/rubber trim around the windows have become worn and and kinda rough in areas. When I polished my car last summer the rough texture of the trim trapped some of my SMR (light) polish in it. I was hard to get it out. :rolleyes:
 
Denatured alcohol will usually do the trick for old wax. Or try aerosol brake part cleaner. Then re-dress the rubber.
