Does anyone else find that the saddlebag rails for the RSV/RSTD rust easily, especially around the welds and the rounded curvers? I now have my second set on the bike. Both sets rusted to the point where they look terrible. Any fixes/preventions I'm not aware of? Anyone else have this problem? If I can't get it resolved, I'm just going to take them off, and leave them off. Thanks, Don from PA.
