^what Kris said...
I have a similar camera (a really cheap version though) and have found that mounting on the savage is a pain.
Vibrations cause a wavering video..... a helmet mount is the best and even then the shocks are not the best in the world so if the roads are crappy, your video will be crappy.
If you had a spring mounted shock system for the camera or could make one, that would be the best.
I realize that go-pro has a "anti shake" feature, so you will probably have to experiment with it... keep us posted

Oh, on the plastidip... I did a tourpack with plastidip...it turned out ok, but tends to peel when chipped... I just use a little of the plastidip on a brush to "touch up"...
