This may be a dumb question, but can I avoid sandblasting my cab? I mean, if I buy like 100 40grit discs, can I achieve the same type thing but more man hours? Or is the stupid way to do it? I guess I'm trying to avoid going to the rent place and putting down a deposit and worry about something breaking or something on the dang compressor... any thoughts? I mean, I can see the 40grit discs taking the paint/rust off pretty quick... has anyone ever done this rather than sandblasting the cab?
