Yes, if the bra was wrapped around the edges it would help. I had very few blems until recently and didn't worry about it and then wham! I think it probably came from following some boneheads in the rain who weren't using their mirrors. I could get the bra redone on the hood and fenders but there are lots of little gaps all over the front bumper. Then maybe I should do the entire hood and wheel arches. How about the lower body and the windshield?
In my mind, the only solution to really protect the paint it to vinyl wrap the entire car or not drive it.
I'm not willing to do either of those so I'll live with the blems. Hey, I'm not as good looking as I once was either!
