have you ever hit the frame with that rubber bumpers of the fork?(that rubber on the fork that prevents the stanchion from hitting the frame metal to metal when you over spin the fork or from crash). because when i did a whip on my gambler and that fork rubber bamper hit the frame it made a colour yellow patches where the rubber bumper hit the frame. it might be deferent from your bike because my bike is white, but have you ever had that happen to you bike?(that color patches)
i think ive found where the patches come from. haha
it was the rubber bumpers seating on the frame for a long time, like for a week and could be from the heat of the weather causing the rubber to react with the clear coat.
