Just wanted to share my experiance using gold class, I have a 96 Honda Accord Very Dark green. I applied 1x AIO and 3X SG about two months ago then topped it with p21s. The P21s really did not make any noticeable change. Yesterday I threw on Gold Class and what can I say my car hasn't looked better in years. The dark green became a very VERY dark green. With P21s the car did not look very good in daylight but glowed in the dark. Now the car looks awesome in the daylight. I am very happy pics soon
