Metalman, I sandblasted all of my truck, exterior and interior. I can't see where I have any warping. I didn't spend a lot of time at the same place and I blasted on an angle. Of course if you just keep blasing at the same spot the metal is going to get hot and do whatever. I will give you a few pics next week of my truck that has been sandlasted in and out and painted. Maybe you have had bad results with blasting, but I think it's the way to go if you can seal it right away, the
same with anyway if you go to bare metal.
