Hey,
How did it feel after you washed and clayed it? was it rough? or smooth. It should of felt smoother than before doing anything to it. If it did feel smooth then maybe you have some wax left over that you cant see, but you can feel. Also was the pad you were using clean? Was there anything stuck to it that you might have missed? There could be alot of things, but remeber this.... It will only look good if your preperation is good. Just somethings that came to mind. Hope it helps. And by the way :welcome :dcrules
