9. This vintage dual-point distributor was looking dull and drab after decades of non-use and storage. An initial pass with grit and glass cut the oxidation, and a second pass with soda cleaned up the housing nicely. For comparison, the unblasted area is to the right. We stayed off of the original ID tag. Glass bead would be good for cutting rust from the steel cap hold-downs, but they should be removed first and blasted separate from the softer aluminum housing.
