Well I went to HF and bought a small pressurized sandblaster yesterday. I have 2 frames, my 1984 Miyata 610 and I added my 1983 Schwinn Super le Tour which I am considering for a 650b conversion. Set up outside and had a bit of go with it this AM. Had some clogging issues but started getting the hang of it. I must say it zipped right through the paint and rust!
