Yeah i've been thinking about doing mine and have an idea on what i'd like to paint on the top. The bitch is that I don't have a spare gasket and don't really feel like taking it off the car, i'd rather drive it.
Doing it right on the car is impossible. So i'm keeping my eyes peeled for a spare cover or at least waiting 'til I have the car put away for winter again in a few months to do it...
