Think twice before you acid dip. Carolina chem-strip is the only place I know of and they are north of 1500 for the car and all the panels now. I strip them with a citrus stripper first and then go with a media blaster. After acid you have to be very careful to get it neutralized or it will bubble the paint and rust the seams. All the rust preventer is now gone from in the weld seams. Soda blasting is the best if you can find someone local. I take them the car on the rotisserie so it is easy to work on and they use less time. Saves money when they charge by the hour.
