My 4/4 is almost watertight roofwise.
But water enters through the floor, so I always remove the carpets after driving in the wet.
The glove compartment is another wet area, but I suspect this has been cured after I replaced the gaskets around the windshield wiper exit.
But when using the window washer fluid with roof up, the wind will squeeze it into the corners where it will end up on the occupants in my Mog.
So I use non alcohol washer fluid.
