OS-P4: The Secret to Rehydrating, Restoring, and Protecting Plastics.

Gray plastics give away a neglected car even when the paint shines. The sun eats them first: trim, dash, bumpers.

OS-P4 rehydrates them and brings the color back, with UV protection so they don't fade again a week later.

It's the step that separates a clean car from a cared-for car.
