what are the differences between the different blastings? (glass, bead, sand) i am wanting to media blast my TPI setup to get it ready to be powder coated, but not sure which one to use for i don't know what the differences are heh

 

The different blast media are for different types of materials you are basting. For aluminum parts(like your TPI plenum) you would want to use glass bead. You can get info and purchase this and other media (crushed walnut shells, aluminum oxide, etc.) at Eastwood's website, here is a link. www.eastwoodco.com
