You have to use low pressure or you will warp sheet metal, like 90 psi
or less. I like Dupont Starblast. Takes it off quickly. I do it
outside on a driveway and put up a crude fence to catch most of it. I
sweep up and reuse the media, so I can usually do a car body with about
3 bags. I think they made them cheaper as they went along, because my
TR250 had color on all the surfaces, top and bottom.
