I bought a soda hopper for the side of my skat blast cabinet. Just change hoses in side the cabinet. Uses same orfice as glass. The fan sucks most of the used soda out, some mixes in with the glass in the bottom of the cabinet but gets sucked out with a little use of glass. Works very good on aluminum turbo parts without etching them. Will remove carbon from heads and pistons quite well also.
Used the T3 Melamine media to clean up some hardware on the Harig Super 612 I'm trying to nurse back to life, and really pleased with the results. These black oxide finished thumb screws are from the slip rings on the dials. They looked like crap, but before just replacing them, decided to give the plastic media a try. It stripped the surface rust and crud right of almost instantly, and didn't touch the black oxide.
