As your ride's exterior ages, rubber, plastic and vinyl of all colors will dry, crack, flake and deteriorate. This oxidation can be stopped and reversed with Mothers® Back-to-Black® Trim Care, our favorite auto care concoction. This trim treatment is great for bumpers, moldings, louvers, window trim, vents, seals, skirts, door handles, wiper arms — anything that's uncoated plastic, rubber or vinyl. Apply Back-to-Black® to sunburnt plastic, rubber and vinyl to revive the factory-new sheen, and then re-treat regularly. Size: 8 oz.
