Re-Volting is a trademark for rebuilt alternators and batteries, for when cars' alternators start to fail. Davey Apex, the Piston Cup racer, beared this sponsor, as well as Davey's reserve driver, Bashman. Between Cars and Cars 3, T.G. Castlenut replaces Davey Apex and has changed from 84 to 48. But, T.G Castlenut was replaced by Aaron Clocker. In the 1950's Re-Volting sponsored LeRoy Newing with the number #300.
