I personally, as in my opinion, don't like the trim dressing's or Back to Black all that much. I hate that it tends to "drip" or "run" when it gets wet. In my case I washed car, waxed, made it all pretty then applied Back to Black. Next day it rained and had that oil streak look going on. I thought I used it spareingly too. I noticed it more on my truck as there was a whole lot more surface area on the mirrors and bumper trim. Any one else see this?
