Dinodave.........time to do more research on the media and the guy you hire to blast the body.
Soda blasting done by the skilled operator is generally the least likely to damage sheet metal body parts. Watch a few of the shows on TV where the hood or doors came back from the blaster with waves or divots and determined to destroyed. Soda will remove paint and rust it just takes time. The faster the rust is removed the more likely the panel will damaged.
Frame and large heavy parts can me blasted with a multiple choice of media to archive fast removal or rust etc and leave a acceptable surface finish.
If your doing this DIY............Using regular sand has some serious health issue from silica. Yes safety is sissies

Unfortunatly for the un-suspecting blasters silica sand is still sometimes used in the United States of America. A large number of research and hazard studies have been conducted that show the dangers and health implications of using silica sand.
For normal abrasive blasting it is never safe, not even when you are wearing an approved respirator. The only exception maybe in a fully contained blast and vacuum system where all possible precautions have been taken to minimise any possibe chance of exposure to personnel.
Blasting with silica sands, such as beach sand, river sand, and any other crystalline silica sand may cause serious injury or be fatal. Crystalline silica is recognized world-wide as a Class 1 Carcinogen. The silica sand type abrasive media when used in abrasive blasting, typically fractures into fine particles and becomes airborne. When workers inhale the crystalline silica, the lung tissue reacts by developing fibrotic nodules and scarring around the trapped silica particles [Silicosis and Silicate Disease Committee 1988]. This fibrotic condition of the lung is called silicosis.
