Sandblasting the Bed

[Grounded63]

You should be able to have them blast the the top of the rails, insides, frt/rear jamb areas, and the bottom edges/wheel well flanges.

With most respectable/knowledgeable media blast places. You should be able to ask them to only strip the areas. That they know they can strip with out damaging the panels. Usually jambs/edges are fair game. But broader flat/low crown areas are off limits to places that don't specialize in car body's. If inner/interior areas are blasted, that has bracing that exposes an outer skin. The exposed outer skin areas will be heat shinked from blasting. While the outer skin areas behind the bracing will be unaffected. This is one possible issue you need to be aware of, when having body panels media blasted.
