MicroMesh is good stuff. We use it on aircraft window's. As said above.
It work's great on minor scratch's on helmet's also. Ever dropped one<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/frown.gif ALT="
For windscreen start out with the finest paper, 4500 or 5000 can't remember and then follow direction's.
This stuff would also work on cowling's. And your car. Safe for clearcoat.<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT="
It come's with liquid abrasive, Use that and keep paper wet. keep running water over it, and don't rub so hard that it get's hot. Take your time and just work em out. Good stuff.
If Jessie Jame's had a ZX12R I'd ride with him.
