Haven't done any powder coating but I'm looking in to it. Did buy a bead blaster so let me give everyone a warning. My blaster came from Harbor Freight and the instructions said to use a shop vac when using. It came with a connection for the vac or a blank cover if no vac is available. Well, as soon as I got it together I had to try it. Blasted for about 20 mins. and everything was cool. Then I noticed a fine, very very fine covering of dust of everything within 10' of the blaster. Who knows what I inhaled. If anyone does buy and uses a bead blaster be SURE and use a shop vac
