I have a black 300 c. I know its the hardest color to keep clean but when clean its beatiful. I know the spider webs in the paint is normal but I can see lines or brush marks in the clear. And no I dont use a brush when washing. Am I the only one with this problem? And can somebody please let me know how to get rid of this. I wondered if my clear coat didnt have enough hardener in it. PLEASE HELP.
