Im intrested in some info. also. Have not used it yet, but I bought a small 30 pound blaster rig from Northern Tool. My local supplier has sand in 50# bags and 4 choices.
1-white silica fine
2-white silica coarse
3-black beauty fine
4-black beauty coarse
The counter person was not much help, so I bought the white silica fine. Will this do the job on badly rusted and pitted metal? Or should I have bought the coarse?
The black cost twice as much.
