Sand blasting does generate heat. It is possible to warp body panels. I
wouldn't worry about the BH though. Just vacume the heck out of it after
wards, then wipe down with copiuos amounts of laquer thinner or some such to
remove any residue. Then etch prime imediately, or else it will rust within
hours. The big problem with blasting some parts is ensuring that the dust
from the process gets out of all the cracks and crannies, otherwise the
second you hit the triger on the spray gun, the surface suddenly looks and
feels like sand paper. When I disassembled my BH I used chem paint stripper
and then sandblaster the rust spots.
AT the resto shop we had a blaster that mixed water into the stream. Theory
was that it cooled the metal and prevented warping. Seemed to me that what
you were really doing was injecting water into the freshly exposed steel.
Surface rust would start before the parts was even dry.
