- "Lightning McQueen here. And I use Rust-eze Medicated Bumper Ointment, new rear end formula! Nothing soothes a rusty bumper like Rust-eeeze."
- —Lightning McQueen in a TV advertisement
Rust-eze Medicated Bumper Ointment is a bumper ointment company who sponsored Lightning McQueen in Cars. McQueen at first looks down upon the people who run Rust-eze and is planning to ditch them and go with Dinoco as soon as he gets a chance, but has a change of heart after his life-changing experiences in the town of Radiator Springs, and decides to stay with the company. The product was created by brothers Dusty and Rusty Rust-eze and is somewhat a "rip-off" as the commercial states: "Actual results may take up to 36 weeks", which is about nine months.
In the Cars Die-Cast Line, there is a Lightning McQueen released with a can of Rust-Eze. On the back of it, there is a pledge as follows:
- "Get speedy, soothing, wonderful relief from the pain and discomfort of rust. Fast-acting Rust-eze contains up to 2 1/2 more Eze for quick soothing relief. We promise."

- In Planes: Fire & Rescue, Mayday states that he takes Rust-eze Medicated Bumper Ointment.
