I've also read that is a possibility. Will be taking my bike on an 800 mile round trip atop my station wagon and I plan to protect that area just in case. Will remove my utility kit and computer (just because its easy to do so). If I go through a pouring rain I will just have to deal with it and dry and re lubricate as necessary. I do occasionally wash the bike down with a hose anyway. Still looks beautiful after 3 years.
