Adam's Black Trim Restorer is a temporary dye coloring to bring back a nice dark color to faded exterior trim pieces. Black Trim Restorer applies easily with a Microfiber Applicator Pad, or our Ceramic Coating Applicator, which works great for tighter spots. You will want to make sure the trim is as clean as possible before applying this product, so we would recommend wiping it down thoroughly with Eco All Purpose Cleaner or Tire & Rubber Cleaner first. Applying is simple and easy - pour a few drops onto the applicator, and carefully spread it across the trim piece in a nice even motion. Black Trim Restorer is a game-changer for those plastics that just don't seem to want to get perfect again, and it will last a few months per application too!
