To ensure a smooth application process, start by thoroughly cleaning the area where the trim will be applied using a clean cotton cloth and wax as well as grease remover. Next, install the trim carefully, making sure all pieces fit without removing their backing. Additionally, when installing narrow components or corners that are mounted on vertical surfaces, use an adhesive promoter for optimal adhesion. After completing the installation of all parts, inspect the kit meticulously to guarantee a proper and secure installation.
