bead blast sand substitute

DUDE!!!! thanks a millon, it's funny i went to harbor freight also and bought the EXACT same blaster. i have to wait a couple of weeks to get started on the clean up of the wheel wells due to bills & family coming first..... i'm going to use my grinder with a wire wheel on it mostley and basically use the blaster to get those hard to get places that the wheel can't reach. I'll see if home depot/ lowes carries it then check with Ace, I dont think we have true valves here in phoenix. (i should just go to the desert and get some sand there, LOL, I wish) thanks a ton you have been a HUGE help!!!!!!
