Need some help from a rust guru!
Blast only the structure do not blast the quarters , roof, doors or fenders, or hood inside or out unless severely rusted and then only do the rust. When we blast a car we only to the structure to clean it we never Blast ,DA. or grind paint off. Most body guys do it because its easy to Da a car down or feather edge it. I run over the body with a DA and 220 before epoxy prime but never remove paint with the DA it will build heat. But most important if you paint strip the car it removes all the body work and you can actually see what you have and where it was sanded prior to you owning it. A DA will only cover those previous sanding marks and you will never see what was there. This Duster was blasted Only the rockers to remove the paint and rust under and on the pinch weld. We did only the bottom of the one quarter and the front sub assembly. The car was mostly rust free .
