I have been using Black Wow for several years. I have been a fan even when others have been less than enthusiastic about it. A week ago I applied it to the plastic trim on my 2006 Range Rover Sport. It went on easily, I use a pad that I keep in a plastic bag with the black Wow bottle. The pad is pretty saturated with black wow. We had two days of rain a couple of days after I applied the Black Wow. It did not hold up at all. The trim looks very very streaky and blotchy. Time to reapply. Thankfully it rarely rains out here. It does hold up fairly well during hand washes but evidently not those by Mother Nature.
