Im not sure I see any real advantage to this over using low air pressure and #10 Beads. Adding water may make it cleaner. convince me
Glass media needs a conversation starter, especially with regard to size:
https://www.mediablast.com/sandblasting-glass-bead-conversion-chartDo not confuse glass beads with chopped up glass (like harbor freight uses). One is actually a ball -- the other chopped up glass.
So a "#10 U.S. STANDARD SCREEN SIZE" is just a bit finer than the BALLOTINI AD I use. And I also use about 25 psi on finer items.
I like Vapor Blasting. Cool tech. But if you have a media blaster you can do some really nice work with the beads. Heck, I bought some Ballatoni beads on Amazon, but have found a local source for half price. Plus the receptionist ...
Here are a few examples with a before/after of a SJ washer bag bracket (sold) and a distributor I quickly blasted. I didn't blast the whole thing, just quickly did the front, mostly near the top.
Like I said, I like vapor blasting. And I'm glad a service is being offered for those people who want to send out a bunch of parts and be done.
But don't discount glass media.
