Thanks Guys. I din't mention names, but Steve was the person I spoke with. He does have a very praiseworthy reputation. I realize that the rear of the booster isn't seen when installed (between the attachment brackets), but wondered when it came to a restoration just how involved the process became. Pit removal is an extra charge by the hour. Pit removal is a labor intensive task, and requires many hours of ro-loc sanding, edge tapering, and buffing.
I decided to tackle this phase of the project myself with many years of rifle barrel installation, fluting, and the associated (in the white) buffing and polishing to get it to a mirror finish. The booster doesn't require a mirror finish, but does need to have a uniform smoothness before zinc plating and the zinc dichromate coating is applied.
