Hey there! Using this carbon fiber hazard button overlay is super easy. First, make sure the area where you'll put it and the overlay itself are around 70 - 80 degrees. This helps the adhesive work better. Clean the area well. You can use an alcohol prep pad to get rid of dirt and debris. Don't use Armor All as it might mess with the sticking. Before you fully install it, test fit the piece to make sure it's in the right place. Once you're happy with the fit, remove the backing and stick it on. Press down evenly on the overlay to make a strong bond. And here's an important tip: always triple - check the orientation before you install it. As for maintenance, just wipe it gently with a soft cloth. This way, your overlay will keep looking great and last a long time.
