From the number of similar experiences posted, it seems that we just need to accept the advice "It's a bumper after all" and get used to blemishes after smoothing them out as much as possible and applying touchup to reduce the contrast with the undercoat (or dark plastic base material). I've done this with my Super White, even pushing out a 3-inch, 1/2 inch deep dent. You have to get in just the right position, or know where to look for it to notice. Anybody else notice how much less we worry about diagonal parking proximity once the first ding appears on the doors?
