I've helped build quite a few race cars, and I'd stay completely away from acid dipping a car. I've worked on two and it was not worth it. Caused massive problems with the chassis, you just can't get the spooge from the tank out of all those little nooks and crannies.

Soda blasting is way more controllable and IMHO does a better job for pre-welding. It also produces a natural resistance to corrosion.

I helped on a Mustang done this way and the soda blasting guy came to our shop and blasted the whole chassis for like 350 bucks. Made the welding easy. We used POR to paint the underside of the car.

Just a opinion...
