When I worked at a Mopar resto shop, we'd send out bumpers to a local shop that I thought looked like crap. We'd get them back, and they looked perfect. I have no idea how they get them that way. They must have a template, or something, because a twisted pretzel is what they were given, and what we got back fit perfectly. You could see where they beat it on the back side, but there wasn't anything that looked like there was a bunch of filler on the other side. So, a good shop can work miracles. The price was around $400, if I remember, but that was 20 years ago. Rechromed bumpers will look perfect. Repros will look like new bumpers. What I mean is, there will be scrape marks where the bumper was forced through the press, and these will be removed on a rechromed bumper.
