Hi all...I've read the previous posts regarding NuFinish and have been personally using it on my vehicles for years. I've never had any problem with it affecting the paint and really prefer it because of it's durability (2 applications in the fall and it's still there after a salty winter and all of the washes...don't like to wax that often). The problem with the stuff is that it stains vinyl trim something awful...despite my best attempts, I have some really visible stains on the (unpainted charcoal gray) bumpers and trim around the windows. I've tried everything to remove it and have yet to find anything that works. Protectant makes it "disappear" for awhile but it reappears as soon as the protectant is gone (currently using 303). Any ideas for removing these stains?...Thanks
