Several weeks ago I was checking my roof out on the VX and noticed significant rust at 3 places along my rood rack. At one spot it is all the way through 1/8 inch wide. Rust usually forms in the same place on models. I will have to take this bull by the horns but I'm not sure how. Probably remove the entire rack and run a fiberglass strip down then paint and replace the rack. It is very discouraging. For the moment I am embarassed to say I grabbed household calk and covered it - just to keep rain out for now. If anyone has any experience with this one - please chime in.
