First Generation Firebird-L Mailing List ......................................................................... My body guy had the car soda blasted. He prefers the soda because it is (he claims) a little easier on the metal, and it disolves in water therefore it is easy to rinse out of small crevaces and hard to reach places. On the other hand, a friend of mine who had his body sand blasted is still vacuuming sand out a year after the car has been on the road, shaking it out of the trapped places. He plans on dipping his next project.
Just my experience with it.

I think you are missing the point about soda blasting. It does not have those problems that other media has. You can leave glass in the car, it won't affect rubber, it won't get very hot and it's not heavy enough to warp metal in the manner you described.

Your story is an example why one should not farm out media blasting to anyone. I started with really rotted stuff for practice like a battery tray that wouldn't be saved and was reproduced. . I discovered that it's easy to keep blasting at rust when it ate through much of the panel. It is like taking millions of small body hammers and beating hell out of your car. The most you can to with blasting is to remove surface rust that will cause paint failure. If it needs more than that, metal needs to be cut out and replaced. I have read many heart breaking stories about sandblasting or media blasting ruining panel straightness. Potentially expensive and restorable cars have been ruined, many of them more valuable than a Firebird or Camaro. I have read even more discouraging stories about finishing a car that was soda blasted and having the car for a year or three under final paint. Then the soda, which is chemically active in various nooks and cranies is still in their causing failure. I would not touch soda blasting with a ten foot pole. It is bad enough to get media out of the project. It is much smarter to chemically strip the car, then run a d/a sander and as a last step, and if necessary, give it glancing cleanup with a sandblaster you run at home. A sand blasted panel cleaned up from OEM primer and paint will be stretched from the equivlalent of hammer on dolly beating. This can be corrected with a shrinking disc if it is not too badly damaged. My advice is don't abuse the panels like this in the first place. The s message is the guy who blasts tractors and farm parts should not be any where near your classic bird. If you have media blasting done, it has to be done by the same guy who has turned out winning results on expensive cars. I am convinced the first step is chemical removal of the finish so the metal is not abuse more than necessary..
