I know this is a tired subject but, I had the dreaded peeling roof trim on my 1994 850 Turbo. After reading the different threads here I ended up removing (carefully) both trim pieces. I then found a good open area to support the pieces and used my handy dandy Dremel Tool with a sanding barrel attachment (fairly course grade) and stripped off all of the black material. I used probably 4 sandy barrels as they wore down quick. I then taped off the rubber stripping and used a Bumper and Trim Spray Paint (flexible stuff)to paint the the trim. I let it dry overnight, then re-attached, and whala, it looks like new. I think I'll keep it for another 100,000 miles, maybe.
