I painted mine tonight with Krylon Fusion, semi-gloss black. It looks good. Actually, its better than the plastic Kawasaki ends it slides in to.
Nothign difficult about removing the plastic panals for access other than two of the plastic phillips head rivets refusing to back out. I was able to put sideways pressure on one of them to back it out. The other was accessible from the opposite side. On a 70 degree day the paint was dry in 15 minutes. Not completely cured, but dry enough to re-install.
The sunlight was shining directly on it, but the color is actually very uniform. If you have not tried the fusion, it sticks to plastic (and plastic contact lenses) very well. I had a friend do all the plastic on his dirt bike. Its still holding up after three years.
