Using this license plate panel is a piece of cake. First, find the right spot on the rear of your 2015 - 2021 Subaru WRX or STI. Then, peel off the backing of the 3M tape on the panel and stick it firmly in place. It should take only a few minutes. Note that due to packing, the panel might not be super shiny at first. After installation, grab a light rubbing compound and a microfiber cloth and gently rub the panel to make it look brilliant. For maintenance, just clean it regularly with a mild car cleaner and a soft cloth. This will keep it looking great for a long time.
