When I had my panel done I think they just used sand. The place I used does tons of cars and trucks, I didnt worry about them warping anything.

Just take it to someone that does a lot of cars. Most places that do this also have a ton of pictures hanging on the walls of the cars they have done. Its good advertising, and should make you feel better =)

I just remembered, my 58 Ford wagon was also blasted there. The previous owner had them do it. Once again they used sand and the thing looks great, well except for the fact it has no paint lol.

And like others have said, if you have it done with soda you really need to clean it good afterwards, and make sure you get it out of all the little crevices.
