So I've been tired of looking at the stock rust color undercoating that is also peeling off. It just makes the 4 show it's age. So I stopped by auto zone and picked up just two cans of the 3M for $10 a peice.(One can took care of the front two wells, one for the back two) And resprayed my wheel wells with the product. I mainly did this for visual purposes, but it ended up slightly reducing noise from the road aswell. The first picture is a before, the second picture is after about 2 weeks daily driving, in hard rain and just plain old sunny days. It is wet in the second pic but it is just as black, dry. I am very happy with this for only 20$
