When is it good to Sand/ Media blast your car?

Not sure what direction you want to go with yours but i just got off the phone with a local blasting company, to just have the engine compartment, trunk and undercarriage done was around $300 here. To me the danger of warping panels far outweighs the time and effort it takes to strip body panels down by hand. especially if yours is fairly rust free my vote would be to just strip it by hand. Of course thats just my two cents :)
