Al’s Liner Vinyl Flattener boosts the durability of your liner while delivering a custom semi-gloss or matte finish that can be difficult to achieve with traditional protective coatings. It’s perfect for applications that require a full strength, non-reflective coating, and has been widely used by our Kustom Kulture customers looking for that matte finish for under coatings and chassis parts. The biggest advantage of our Vinyl Flattener additive is its ability to increase the hardness of our bed liner. The natural urethane/acrylic combination offers a more rubberized coating which provides extreme non-skid properties but is pliable if applied with enough thickness. The natural material in every Al’s Liner Kit offers a Shore Hardness of 82 Points Type A, giving it a hardness that exceeds an automotive tire tread by about 20 points. With a full batch of Vinyl Flattener (1 quart per gallon of Al’s), you will see an increase to a 92 Point Type A Shore Hardness, which delivers maximum protection against nicks, dents, scratches or any other accident that might damage your vehicle’s perfect finish. With the Al’s Liner Vinyl Flattener Additive, the DIY Truck Bed Liner Kit can duplicate the appearance and hardness of polyurea bed liners on the market without the trouble or severe price of an in-shop job. If you want maximum protection in a tailor-made finish that you can apply at home, Al’s Liner Vinyl Flattener Additive has you covered.
