Sand Blasting Car -- what would you do?

Don't know what type of blaster you're considering - pressure or siphon. Definitely get the pressure blaster. Work will go a lot easier and faster with the pressure blaster. Siphon just takes forever. It's been quite awhile since I've blasted a car, but IIRC it shouldn't take much more than a hard, sweaty day under the hood (sweaty even in the winter). Worst thing will be getting ALL the media out of the little cracks and hiding spots inside the car. After you're done, you'll probably wish you would have paid someone to do it lol!
