A car painter told me he does not like to paint cars that have been "soda" stripped as there are adhesion problems because of the soda. I am not sure if he was talking about the soda itself or the fact that the soda does not "etch up" the metal like sand or plastic beads do.
I have had others tell me that the soda leaves a film that needs to be rinsed well before priming.
Any personal experiences out there??
