Thanks Neil for the explanation on how you were successful in blasting your cab. I just spent approximately 2 weeks removing by hand all the paint and rust on the outside of my cab. I used everything from a D/A sander,palm sander with 80 grit paper to a 3m curly wheel on on my drill. Oh yes also loosened up the paint with citrus stripper which worked quite well. Now I would like to blast the interior. Based on the compressor you used my 3hp coleman 20 gallon should do fine.Thanks to your explanation I feel confident I can proceed with the interior.
