Windshield sealant

We purchased a used Beaver Marquis which had an annoying air leak on the lower drivers side of the windshield. Used Duct tape as a temp fix to get it home and am wondering about suggestions for a permanent fix.

Air leaks are not that uncommon. We've had several fixed by having a auto glass company use windsheild sealant around the factory gasket. Eventually the gasket gets hard and doesn't seal as well, so unless you want the expense of having the windsheild removed (maybe broken-they don't guarantee not to) and a new gasket installed, try the sealant route with a glass installer first.

Don't use or let anyone else use silicone!! Nothing sticks to it and it's really hard to remove.

The shops use polyurethane when they install the windshields.

If you want to seal it yourself, don't bother trying to use silicone. It won't stick to the rubber gasket.

I have used Loctite 'The Right Stuff', available at most auto parts stores. It is marketed as a gasket maker. It adheres very well to the rubber gasket, and also to the glass. It is as easy to work with as silicone, and is very strong. It dries much the same black color as the windshield gasket.

I reccomend 1-part polyurethane sealant.
This company has a window installation kit that might have what you want.
