Using these mirror trim overlays is easy. First, clean the surface of your mirrors to make sure there's no dirt or dust. Then, carefully peel off the backing of the overlay and align it with the lower part of the mirror. Press it firmly to ensure it sticks well. When it comes to maintenance, just use a mild car - cleaning solution and a soft cloth to wipe them down. Avoid using harsh chemicals as they might damage the carbon fiber. Also, be gentle when handling the overlays to prevent any scratches or dents.
