I sent a bonnet for a BMW 2002 to be blasted once. It came back all warped from
too much PSI. If you're having sheet metal blasted, be sure they don't over do
it, or it will just make matters worse.

You can readily predict the effects of sand vs bead blasting by
examining the blast medium. Silica sand is composed of long pointy
pieces of hard rock (not like beach sand) while glass beads are much
like crushed sugar at the outset, and like icing sugar when exhausted.
Sand really tears into a surface, while beads (or plastic or walnut
shells) shock the surface. Yes, cleaning out the beads is a bit of work,
but you'll really get familiar with the frame of your car when you're
done clearing out all the crevices. :)
I've read that walnut shells can leave a somewhat oily residue.
