Yeah, that's the problem, it depends on what the ingredients are in the plastic. The 2 other pieces of plastic at both ends of the cowel are fine.Ive done it to my black plastic fender flares, front and rear bumper, and mirrors and it made them look new again, not faded...maybe its the type of plastic?
It worked well on my 95 Pathfinder with plastic fender flares. It didn't stain that, nor did it stain the plastic on my 06 Pathfinder roof rack. Just stained the cowel.Thats too bad, I never tried it on my cowel so I can't speak about that, but it makes the mirrors and flares look REAL nice on my 97...
I do know that there are products designed specifically for plastic, we had a bottle of it we used to use on my moms old CR-V (with the half plastic half paint look) and that stuff looked AMAZING for about a week
haha, sounds like you are fighting an uphill battle!! When I go home this weekend I will see if the bottle is still laying around...It worked well on my 95 Pathfinder with plastic fender flares.

There's a product out there, I think it still is, made by Turtle Wax. It's used on exterior plastics only. Well, tried that stuff a long time ago and remember it did turn the plastic trims darker for a long period of time, but it also attracted dust and sand.
Used it once and threw out the rest.
