I tried sandblasting once when I had access to a jeweler's sandblaster, It took off the paint with ease, along with every other detail, like doors, hinges, fans, exhaust stacks...you pretty much had a slighlty curved hunk of plastic when you were done. I was testing it on an old Tyco shell so I didn't shed too many tears when it was done. As long as you're good at desoldering and soldering, a jewlers sandblaster works great on brass, but you have to take all the soldered details off first or the sandblaster would remove it for you. I did this once and the brass engine looked better than new when you followed up with some blasted rouge.
The media material was too hard for the plastic shell. When using a media blaster to take paint off of plastic I have always used baking soda. It won't hurt the plastic as long as you are not blasting directly into the plastic. Keep it at a 45-60 degree angle.
