My bike has been uncovered for a long time, and the sun combined with poor maintenance has led to some less than desirable looking parts. Trying to get it back in tip top shape again, and hoping for advice. The tank is super yellowed except where the stickers have peeled. Can add photos of this later if needed. And my fairings have this really stubborn grime. I tried clay bar, maguire's plastix, and 303 protectant. Not at the same time, lol. And it helped but they still look like this. Is there any hope?
