sandblasting plastics???

i have a few interior pieces, that i was wondering if i can sand blast them, instead of sand them… one thing is that they have small crevices, and are impossible to get into… but could anyone tell me if you can sand blast the interior pieces, and if so… who does it??? thanx in advance…

I sodablasted j_espo’s plastics and they turned out pretty good. You can PM me if you have any more questions.
