How is it done? I have read that products like etch-all don't work on boro. When you want an etched finish, do you use a sandblaster, or gem tumbler, or what?
I have seen $100 dollar plus for small sandblasting units. Is this the sort of sandblaster one would use for boro? I am nowhere near the point of getting into equipment, just kind of asking on a hypothetical level at the moment, of how boro workers typically get an etched finish. Doing a forum search, I just got threads that were back and forth regarding whether etch-all works or not
Thanks a bunch!
