I replaced my rear glass a couple months ago and my glass guy said not to use the sealant. We discussed a length how the factory manual recommends it but he said with how tight the glass goes in it was not needed. In the end I agreed to give it a try his way with a commitment from him he would redo it if it leaked. It rained a ton here over the past few months and no leaks. We'll see long term though. Hes been in business over 30 years, and I've been using him for 15, so I have some confidence in what he says.Does anyone know off the top of their head if the 3M urethane sealant above works for the rear window too? I need to replace my gasket.
But to answer your question, the 3m windshield adhesive will work for the rear too. Just be sure to get adhesive and not sealant. Sealants are typically silicone based and won't hold up as well.
