This overlay is easy to use. First, make sure the area where you'll install it and the overlay itself stay at around 70 - 80 degrees for a while. Clean the area well, getting rid of dirt, debris, and stuff like Armor All. You can use an alcohol prep pad for a better clean. Test fit the pieces before you start. Then, take off the backing from the double - sided adhesive and put the overlay in place. Press evenly to make a strong bond. As for maintenance, just use a soft cloth to wipe it clean. Avoid using harsh chemicals as they may damage the gloss finish.
