Sand Blasting Car -- what would you do?

I think I would just sand blast the rusty areas,anything you can do with a sander or chemical stripper will reduce the warpage,on larger flat panels blast at an angle(this will keep the heat down) and keep it moving.my dad did this for a living for several years and seems to be the only on who didn't warp the panels,keeping the blaster at an angle and moving constantly is his best advice and we also used foam rubber to keep sand from the hard to reach areas to make clean up more thorough.wear a mask!!!! breathing silica is NOT GOOD!!!
