The body shop that installed my oem gt3 bumper was also afraid of any aftermarket or even repairs on my oem bumper. I got a great deal $600 on my bumper because there was an area at the bottom that had been repaired at one point, but you can't even tell. Whoever repaired it soldered it with plastic and it looks good as new and appears to be as strong as new. Anyway the shop kept asking me can you return it. I said it took me a year to find it and would cost me nearly $2,000 new. They ended up painting it and it came out just fine. I told the guy your workers need to get a little creative. These guys just want new parts to paint and install, but can't seem to repair. Then on top of that they look for top dollar.
Here is a picture I like to show her off since I keep her locked up at home
