On another thread there is an issue with the trunk gasket leaking. I was thinking about Her Purpleness, and the last time we ran in a rain (From Des Moines, Ia. to south of Joplin, Mo. - about a 6 hour run.) there was some evidence of water in the trunk. It wasn't wet, it wasn't water tight, either. Anyone have any idea of what to replace the rubber gasket with? It would be great if I could replace it with something sourced from an auto parts store or the like. The rig is a 1995 Motor Trike Classic, and the seal is showing a bit of age.
