sandblasting help

[chrismcc2011]

i havent picked the truck up, but it has been sitting for a long time and im willing to bet it has some rust and id like to sand blast the whole thing and start witha a metal shell. i have read that sand blasting can warp metal but i have also heard about sandblasting with baking soda and that it doesnt cause damage to the metal. has anyone used the baking soda method and can give me an idea of what i should do.

im 17 and have no metal work experience so excuse me if my questions seem ignorant to you lol.
