Using your Noble R Style Rear Spoiler is a breeze. First, make sure the surface where you'll install it is clean and dry. Then, use the double - sided adhesive that comes with the spoiler to stick it on. The ideal temperature for installation is between 70 and 100 degrees Fahrenheit. After applying the spoiler, give it some time for the adhesive to set. At room temperature, it'll reach about 50% of its strength in 20 minutes, 90% in 24 hours, and full strength in 72 hours. For maintenance, just wash it regularly with a mild car soap and a soft cloth. Avoid using harsh chemicals that could damage the carbon fiber or the paint finish. If you notice any loose parts or issues with the adhesion over time, check it and re - apply the adhesive if necessary.
