I had all my parts sandblasted and even the hood turned out fine. It depends on the experience of the blaster. I don't think soda will remove stuck on rust. Woody is right that it seems that sand keeps falling out of cracks and such at a later date, but I don't agree with the chemical dip as it may leach out and ruin your paint at a later date. If you look at one of the best shops in the country:
JeffLilly.com they blast (though I don't know if it is soda or sand).
BTW, where are you from in Nevada? I grew up outside of Carson City, went to Douglas High.
