Using this high - heat tape is a breeze. First, pick the right size for your project from the 20' x 20' sheets or 2' x 15' and 2' x 30' rolls. Then, clean the surface where you'll stick the tape to ensure a good bond. Peel off the backing of the self - adhesive tape and firmly press it onto the area you want to protect from heat, like wires, intakes, or the firewall. Remember, this tape is for radiant heat prevention, so don't let the exhaust rest against it. As for maintenance, just check regularly to make sure it's still firmly attached. If it starts to peel or show signs of wear, replace it to keep your parts well - protected.
