Sand Blasting Car -- what would you do?

I did it using sand and a siphon blaster. I bought a cheap sears portable blaster and a 55 gal rubbermaid garbage can. Drill a hole in the bottom and screwed in the siphon hose. I did it in my two car garage. I would do a panel on the weekend and spray it with DPLF epoxy primer. I was very careful with the pressure and didn't warp anything. I had to scrape the undercoat off before blasting. That being said I would not do it again. The sand gets EVERYWHERE! I cleaned that car FOREVER and I will never get all of it out. I would have it soda blasted by a reputable shop and have the rust done with something more aggressive. I was in no rush and attempting to keep the budget as small as possible. In this area I would spend the money.
