Rust-eze is the tire and automotive-care sponsor owned by Rusty and Dusty Rust-eze in Pixar’s Cars.
The Rust-eze brothers discover Lightning McQueen after he becomes stranded in Radiator Springs. Their company sells a rusty-car treatment, and they offer Lightning a sponsorship deal that can help launch his racing career. The partnership is one of the film’s central links between Lightning’s ambition and the town’s local business community.
Rust-eze is also the racing number 95 car’s primary sponsor in the Piston Cup storyline. The brand’s distinctive orange-and-yellow identity appears on Lightning’s body and on promotional materials throughout the franchise.
Dinoco is a different fictional racing sponsor and is associated with the Piston Cup’s major prize. Octane Gain and Leak Less are rival racing brands. Those names are easy to confuse because all belong to the Cars universe, but Rust-eze is the company owned by Rusty and Dusty.
