Using the Noble Carbon Fiber Premium Entertainment System Trim is super easy. First, make sure your car's interior temperature and the overlay are around 70 - 80 degrees for a good while. Clean the area where you'll install the trim well. You can use an alcohol prep pad to get rid of dirt and other stuff. Do a test fit to see if it's in the right place. Then, take off the backing and stick it on. Press evenly on the overlay so it sticks firmly. As for maintenance, just use a soft cloth to wipe it clean. Avoid using harsh chemicals. If you notice any issues within a year due to manufacturing defects, you're covered by the warranty.
