Hello all. I gave the new to me `04 Discovery II its first bath today and noticed water got past the rear tailgate door. All the rubber gaskets/seals and such appear to be in place. There were droplets on the inside of the tailgate window and the rear section of the rubber mat was wet so a fair amount of water got through. Is this a common problem that I simply need to live with or is there perhaps an issue to diagnose and correct?
