bigchevy3600: regarding cost can depend on the type of media. If your talking sand blasting I get "blasting sand" from the local concrete mixing folks at about 5.50 per 100lb bag. Then it depends on how bad a chassis or part is before you start. Recently a 68 pickup chassis took us about 350 lbs using a small pressurized blasting pot. If you use a siphon blaster you will use/waste more sand. I'd figure about 600 lbs would do it all but again, depending on how bad. I finally got around to ordering my 20 gal pressurize pot and it should be here this coming week. I'm anixious to see how it does on my panel chassis. I'm about 3 months behind on this project but will catch up! I might add that other "media" will definitely be more expensive. I use glass, aluminum oxide, garnet and some other stuff in my bead blasting cabinet but that stuff runs from $19 to $29 for a 50lb barrel. Hope this helps answer your question.
