Fleabay and you may even try amazon, I scored a winshield for my XR from a dealer on there for 80% off the msrp back in the summer. As far as touch up goes I would let a professional do it because of the 2 or 3 layers of paint used on these bikes. I had a rig swerve off the shoulder in front of me down in GA and peppered me with gravel, taking 3 small chunks of paint off my left saddlebag. I tried touching it up but my sunset red has black underneath it the result was my touchup was more noticeable than just the missing paint.
