my 2c worth,
currently the missus is getting here car done professionally, the restorer says he will NOT touch a car that has been soda blasted, as getting it soda blasted does NOT kill the rust like bead blasting it (with the correct mix of bead) does. It all may look well and good but in the end its only masking the area that have rust on them and there is every chance down the track that rust can reappear.
So for us with her car there is not chance that we were willing to take for soda blasting over bead blasting. As getting the car done that we intend to keep for the rest of our lives then bead is the only way to go.
Yeah my and my restorers 2c.
Cheers
B.
