As your ride’s exterior ages, rubber, plastic and vinyl exterior hardware of all colors will dry, crack, flake and deteriorate. This oxidation can be stopped and reversed with Mothers "Back-to-Black", our favorite auto-care concoction. This trim treatment is great for all sorts of exterior hardware in all colors-bumpers, molding, louvers, window trim, vents, seals, skirts, door handles, wiper arms—anything that’s plastic, rubber or vinyl. Apply "Back-to-Black" to sunburnt plastic, rubber and vinyl to revive the factory-new sheen, then re-treat that exterior hardware regularly. Choose from the 12-oz. wipe-on formula, or the one step spray on 10-oz. aerosol can.
