I am using the Norton system to buff out a gloss black single stage urethane paint job. I have sanded the light orange peel with 800, 1000, 1500, 2000 and 2500 grit paper. When buffing, the black coat is now cloudy and shows different hues where the orange peel was sanded out. Its like the paint has gone on in layers and each layer is slightly different. It looks horrible in the sun light. What am I doing wrong ??
