When I get to the point where the paint has to be removed, I have all the "hard to strip" areas, like interior, bottom of the car, trunk, the bed of the El Camino, fire wall, etc media blasted. I do the flat panels like the doors, hood, deck lid quarters, etc with a spray on paint remover (Captain Lees). I've never had any problems with flash rust after the blasting. I did all the body work on my Chevelle and the El Camino, before any primer was sprayed, and the body work took a couple months. They were both in a dry environment of course. Here's a shot of the Chevelle bottom, and the Elky bed after blasting.
