#3 is what i use for rust and paint removal... but i open air sandblast in my backyard..
it's jsut plain old silica dirt (inexpensive and expendable)
now glass beads etc is whereyou start recycleing it all and getting 4-10 uses out of a bucket....
i would post this question in the paint and body section the guys there know alot more about it then myself...
im a total novice =-(
