But, that is about the time that Gary Riley was bringing state of the art dry ice to the field. There have been some cars presented for Certification that Gary has done, along some done by someone in the Chicago suburbs?, with fantastic results.

Commercial ice blasting is done everywhere, BUT, I would not trust it to anyone lacking extensive vintage vehicle experience. You don't want to lose the FACTORY undercoat and any inspection marks etc. in the process.

Ice blasting is a game changer, maybe Steve will chime in with some thoughts. Sorry for rambling on but I have been considering blasting for another Chevelle.

In the right hands, the process could bring your 67 to a whole different level
