Using this bumper protector is simple. First, clean the rear bumper surface thoroughly. Then, wet the back of the protector with a bit of soapy water. This allows you to easily position and slide the vinyl. For a better stick, use a hair dryer or heat gun, but be careful not to use too much heat at once. Focus on the lead edge which is visible. Center the overlay and push out the water or soap with your fingers. Don't use a squeegee as it could scratch the material. After installation, if any parts come up, use heat immediately to press them down. As time passes, the bond will get stronger and the water will evaporate. When it comes to maintenance, just keep the bumper clean. If there are any marks, you can gently clean the protector with a soft cloth and mild soap.
