Last year when I needed to blast my frame, rims and a bunch of other stuff I came out to my big truck shop and used our Ingersol Rand 185 compressor.
That thing puts out 185 cfm and I use a 100 lb pressurized sand pot. I went through 2000 lbs of sand pretty fast, and I did it down in our sand pit so I didn't have to clean up the mess. This year I built a small catch area so I can blast and reclaim more sand. In order to blast sheet metal I have to stand 3' back to prevent warpage . For sand I use silica sand ( HEED ALL WARNINGS ON THIS STUFF !!!) that I get from my local blacktop sealer company- way cheaper that way instead of buying from home centers. I have a fresh air hood that I wear to prevent breathing the silca particles ( same one that I use for black beauty sand as it has silica too ). At home I use two 5 hp compressors rated at 11.5 cfm each for my blast cabinet , that does a good job of keeping up. If you have an aluminum compressor it won't last too long if it has to run constantly you might want to put a electric fan by it to help cooling. If you can find someone that can blasts with a large compressor and their prices aren't too steep it would end up saving you a bunch of time ,money and headaches cleaning up the mess.
