I was looking for another reversible alternative to plasti-dip. I then came across the BMWShadowline product. Appears to be very highly regarded so I figured I would give it a shot.
BMW Shadowline Matte & Gloss Black Window Trim & Roof Vinyls
I ordered 2 4" rolls and one 5" roll. Should come in this week. I plan to cover the trim, the chrome on the rear step, the chrome on the front lip, and potentially the center pillar between the windows. Right now the center pillars are gloss black and they are the only gloss black on the vehicle. To match the trim I figured I would try to use the matte black and if I don't like it, I can just remove it.
Last, but not least (and this is the aggressive one) I think I am going to try the door handles. Again, if it doesn't work, I just remove it.
