Showroom New Plastic Trim Dye Showroom New Plastic Trim Dye is an excellent auto reconditioning product to restore the original color of faded plastic and vinyl exterior trim. It will not wash off like silicone dressings do. Plastic trim fades and becomes discolored in time. Plastic trim also gets polluted with wax if the person waxing the vehicle is not carefull. Showroom New will restore the black or grey exterior trim on door handles, fender flares, running board inserts, bed caps, even pick-up truck bedliners. Our grey is excellent for the trim on Volvos and PT Cruisers, Avalanches, and Jeep Grand Cherokees! Shown here are some great before/after pictures. Automotive Plastic Trim Restoration
