Man I wish we had something like that in Seattle! I sorely miss working at a shop that had a cabinet big enough for bike frames. I even blasted tandems, with a sort of tent built over the open door on the side of the cabinet. Blast the front half, flip the frame to blast the back half.

Not only is getting blasting done, by the one place I found, way expensive, but I don't trust them with the thin tubing I prefer. I would have trusted them with the steel patio furniture I was repainting, but their asking price was more than the furniture cost new! Luckily I didn't care how it looked so I painted right over the rust. We're more Klampetts than Rockefellers.
