sandblast the whole car???

I blasted my Duster body using Jetmag media. No warpage, and this is the first time I've ever done something like this. Took more time to blow all the media out of the body than it did to blast it. But the results are very nice. Just keep moving, don't get too close with the gun, and use the least amount of air pressure that gets the job done. You can see the gauge at about 80 psi here. See pics.
