Using this protection kit is a breeze. First, clean the areas on your chainstays and rear stays where you want to apply the protection pieces. Make sure the surfaces are dry. Then, peel off the backing of the 3M self - adhesive on the protection pieces and stick them firmly in place. You can cut the pieces if needed to fit the shape of your bike. As for maintenance, just clean the protection pieces with a mild soap and water solution. Avoid using harsh chemicals as they may damage the Ultra - Tough Cube - Tec material. In wet or dirty conditions, the kit will hold up well, but it's still a good idea to give it a quick rinse after a muddy ride. Also, check the adhesion from time to time, and if any pieces start to lift, press them back down firmly.
