Larry, you're thinking of cars that have been acid dipped to reduce the metal and lighten the cars. This type of dipping just strips the old paint and bondo off the cars. The metal does not lose any of it's thickness or strength unless the car is nothing but rust holding it together. Even on rust free cars, this method of stripping is far superior to blasting with sand or beads. Just look at the pictures I posted and you can see how clean the entire body is. I think in the end you will have a better finished product with stripping vs blasting.
