I need to sandblast some frames, not many, and I won't be doing this often.
I'm currently trying to do a local barter for an air compressor (which will come in handy outside of the sandblasting). I've got some offers, but for some pretty low tier compressors. What is the bare minimum of a compressor I can get away with and still be able to use a hand sandblasting gun with its own reservoir? Will I be able to blast at all with, say, 4 CFM at 100psi? If not, what is the lowest I can go before I'm just giving the frames a sand massage.......
I don't mind if it takes awhile, and I realize a smaller compressor will cut in and out on me fairly often.....but anything is better then the tedium of stripping by hand
Thanks for the help!
