Lots of good advice in this thread. Let me comment on what's worked best for me. For smaller parts I use a blast cabinet with various types of media depending on the coating being removed, the material the part is made of, and the finish I want/need on the stripped part. I never use sand in my cabinet. Its too messy and not as effective as media. I use 5 gallon plastic buckets to store my different media in. It keeps them dry and easy to handle. A quick post on craigslist got me an ample supply of free buckets (with lids) from a local sheetrocker. For larger parts that won't fit my blast cabinet I use a pot blaster, outside on my backyard grass. For sheet metal I shoot with soda so not to warp or damage the metal. It also leaves a residue that prevents flash rusting for a few weeks. (Remember to wash your blasted parts before priming.) Any leftover signs of the soda on the grass disappear after the next rain shower. For thicker parts (including edges and corners of sheet metal parts) I spread a large blue tarp on the grass, then shoot with media. The tarp allows me to recover most of the media for reuse. I never use sand because I don't like dealing with the dangers of silica dust. When I have a lot of large pieces, or for a unibody or frame, I'll take them to a shop that specializes in stripping. Next time I think I'm going to check out one of the new mobile services, where they come to you. Has anyone tried one of them? Would be interested in comments on them. Hope this helps.
