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.
If anyone's interested in soda blasting let me know and I can put you in touch. He's mobile too. We're in east central Alabama.

hit the rust with the "abrasive" kit.....it is pricey specially when factoring in the freight costs to Alabama; about 100$
