Discovered today that water is leaking into the rear right passenger footwell. I think it's because the rubber gutter that runs along the top of the doors (on the car itself, not on the doors) is in bad melted shape. I searched, but can't find it online. Should i try to to apply silicone goop or butyl rubber or something? Anybody else have water leak in here during rain?
