Does anyone know how much it costs to get a chemical "bath". I mean the caustic soda , and acid treatment. And, whats the other choice? I've heard something about sand blasting the body,or bead blasting. Any way I wanna strip my chassis down and find where the rust ends and begins. Figure it would be easier to get it all done in one shot. Instead of slowly discovering it over time. I've become so irritated with spending two days on a one day project becouse of rust. Thanx in advance.
