Re: Two is easier then one 1965 GMC S/W/BB build
The dustless sandblasting just uses water along with the blast media. What I have seen done, leaves quite a bit of caked on blast media in the corners and crevasses that is a bit of a pain to take care of. I assume that you are aware that not all blasters know what they are doing on sheetmetal and not all do a thorough job? Also I would not allow anyone to use silica sand as an abrasive. Reason being that not all primers, particularly epoxy, is compatible with a surface that has silica imbeded into the metal. Yes the silica does get into the base metal.
