A guy here in Santa Rosa recently bought this set up. I went to a demonstration last month. He blasted a door panel full power straight on and it didn't show any warpage, the panel was very cold to the touch. It seems as effective as any other blasting. That said I am waiting for him to get more experience on other peoples sheet metal. I am going to have some wheels blasted, seemed to work well.
The question of drying out hidden areas is something to consider. I also haven't had a painter comment on the antirust they mix in to the glass.
