Hello to everyone I do this for a hobby - it all started with fixing and improving airguns, but now I have moved on on firearms recently, I got a sandblasting cabinet, and a 12 gallon compressor, that works on 5 bar. I want to blast a Tok in 9mm, to have a satin finish, but I don't want to use sand - way too dirty - and I am looking to steel beads instead. My question is, to what size of the abrasive should I look for? Tried with soda today, no luck. Any tips are welcome (steel beads are available to me, the rest of the abrasives isn't that easy to acquire).
