Hi Lionel,
I would also like to hear any first hand experiences of using soda.
Everything I have either done myself (in the cabinet, small part) of paid to be done, has been sand medium. In fact I have two wheels at the sandblasters ready to be picked up next week, and another two to be dropped of at that time. Obviously no good around seals, bearings, etc, but I would expect it to be far cheaper to use sand or other non soda medium for large metal panels where no fear of contamination. I have been wanting to get something soda blasted also, just to test the claims. Supposedly, it won't hurt bearings, glass, rubber, etc, so long as it's washed thoroughly afterwards with a liquid to disolve the soda particals. Even good old 'hydorgen dioxide' should do the trick.
Whenever I get the urge to visit the local soda guys, they aren't open, and when they are open I don't have the time to call in. One day the two will coincide, then I can answer the question. In the meantime, somebody here must have used soda, surely?!?!
