I have heard that West Coast Custom Chrome does good work but, I have had no experience with them.
It is sad they have closed.
Probably over a decade now a shop in Wisconsin or Minnesota, I had it arranged through a 2nd party as it was for a '66 Volvo 122S center section. They did beautiful work, straightened several deep dents and rechromed it and it looked like a new bumper. The back showed where they had reformed it (lines from the tooling).The chrome color matched the stock OEM Volvo NOS bumper ends and overriders.
I will ask a friend if he knows the name and if they are in business.
