Howdy Earl,
In my opinion the Soda is the way to go unless you have a bunch of rust. Then the rust needs to be brushed with a sand blaster. Soda blasting won’t do anything for rust. If you can find someone that does soda and sand blasting they can remove the paint/bondo with the soda and brush any rust you have with a sand blaster. Make sure they stay off of the flat stuff with the sand blaster especially if they are using some big monster blaster. An honest and experienced operator is best even if it does cost a little more.
I have never had anything of mine dipped, but…. Say it cleans the entire part inside and out and remove paint/undercoating from all the metal surfaces. I would think it would leave you open for problems on the inside of the doors and stuff where you may have had something like undercoating before where now you have nothing. In my opinion you would have been better off not having all that exposed. “I am not an expert, just in my thinking”. Of course all this is my opinion. I have read a lot on the Stove Bolt and noticed that folks have posted things in other post that has sort of helped me form that opinion.
Soda blasting is really neat in how it can take paint off with out the peppering the metal like sand blasting does. I understand it to be some form of explosion/reaction with the paint when the soda hits it at a high rate of speed. You could take a truck with all the chrome, rubber and glass out to the soda blaster and get it back with clean with no paint left. The soda will not harm even the glass. Plus it will not rust as fast while you’re getting ready to prime the part. I have had a couple of my body parts soda blasted and have been real happy with it.
I hope it helps.
Good Luck!
Michael
