A friend recently bought a commercial soda blasting unit for stripping paint off military vehicles. I just had him blast my front clip and it turned out pretty well - at least now I can easily see what I need what needs work. In my opinion, the soda doesn't really do a very good job on rust. However a big restoration shop that does a lot of soda blasting told me that's what rust is left after soda blasting is solid, cleaner than it looks, and they epoxy prime right over it. I didn't have much rust on this so it won't take much additional effort to clean it up.
