I got an used sand blaster and was reading on soda blasting, what part do i have to change on this set up to use soda? the tip gun ? the tank is 40 lbs, i have a 60 gal air compressor, i would like to do small cleaning on parts for my fj40 project ,maybe later when the time for full resto came i can try to use it on the frame, so what did you guys will recommend?
