Following recent topics on rain and tailgate wipers (and one a little while back on rust on the inside of the tailgate), I am concerned about the build up of water at the bottom of the rear window following what seems to be endless rain.
Surely this is a design flaw and cannot do the paintwork/rubber seal any good?
I know the beading isn't very good - but that's another topic
