Using these emblem overlays is easy. First, clean the surface of your existing emblems to make sure there's no dust or dirt. Then, carefully peel the backing off the overlay and align it with the emblem. Press it down firmly to ensure it sticks well. It should take only a few minutes to complete the installation. As for maintenance, just use a mild soap and water solution to clean them every now and then. Avoid using harsh chemicals as they might damage the overlay. Also, remember that the matte black option is not textured. If you have any issues or need more products for your 2015+ WRX / STI or other models, check out our store.
