The black rubber Water Sprayer that is over the back window of my truck has broken or dry rotted or something, so no the sprayer won't stay in the hole. So now, rain just pours into the hole, I guess to inside of my back door. Has anyone else had this problem? Does anyone know of some miracle glue or something good that can hold rubber to metal?

Marine Epoxy, it holds most things together on my X.

That nozzle at the dealer is an inexpensive part.

I broke my rear sprayer nozzle with a car wash brush. Tried to glue it with a couple of adhesives. No luck in the long run. The rubber hose behind it exerts some spring pressure outward and it eventually worked its way loose. The nozzle is about $35.00. Fixed it right and forgot about it. Expensive but it is done.
