windshield replaced

What did they seal it with?

Silicone is terrible to use on a windshield as it will eventually leak and is horrible to remove if the windshield needs to be replaced again.

just the rubber parts

That is correct! The windshield is sealed and held in place by the "rubber" seal.

COACH GLASS RV Glass Experts in Phoenix replaced mine. No silicone sealant used, just gasket is my understanding. DOES NOT LEAK SO FAR.

Silicon has never been used on Windshields. Not for the main seal that holds the glass in.

Today they use a quick curing 2 part polyurethane.

The closest 1-part material we can buy for DIY is 3M 08693 Auto Glass Urethane.

My Glass installer called that a "Gasket" and they glued every thing in place with a urethane 2 part sealer.

I will add that it depends on how the coach was originally designed for windshield installation.
My rig has a rubber single part rubber gasket or seal that fits around the two peice windshield then other side goes around the fiberglass nose. No sealant is used. When installing the gasket/seal is moistened with soap water for installation.
I have seen later coaches that have the windshield installed using the urethane sealer in leiu of the gasket/seal.

Silicone has no place in/on an RV

Just had my windshield replaced on my 2016 E-450. Was told that because it has airbags the windshield has to be cemented in and they used black windshield sealant. I assume it is cemented so that when the air bag goes off, it does not blow out the windshield.
