Good aritcle but please stop propagating the myth that sand/media blasting causes heat that can warp the panels. I was very skeptical and did a test. I spot welded a thermocouple to the back side of a piece of sheet metal. I then blasted the spot on the opposite side of the metal. The area being sandblasted got cooler due to the expanding compressed air, which more that made up for any frictional heat. Panel warping is actually due to peening of the surface from the high velocity sand hitting it. Imagine thousands of tiny hammer blows.
