Another word of caution. The dust from sandblasting can be extremely dangerous and even deadly. Especially with silica sand. Also the silica sand residue is not compatable with some epoxy primers.

ok i am going to try using play sand that i will dry and sift before i put in blaster. but i am gathering i prob need to buy a canister respreator to be safe. i do have a automotive spray gun somewhere just got to find it. i want to use some kind of primer that doesnt cost to much as i am going to brush on bedliner material for the final coat until i can afford one of those rubber mats that covers the entire floor. so do i just go to oriely's and ask for primer? how long do i have to get it primered after i blast it?
