I have a red one. I got it nasty with mine tailings at Silverton, CO. Took it to the car wash and it came out looking like yours and I WAS PISSED. A few days later the spots just disappeared. I didn't do anything to it. This was last August and even today it looks like showroom. I don't understand it. The flat black, however, didn't and hasn't come clean. New bike and I'm already having to use 303 on it to make it look new.
