Stop in for a cup of coffee

you HAVE to use a sealer on those gaskets, or they will leak...
He installed the windshield and then went thru after and put the sealant under the gasket. I figured he knew what he was doing....

Had a person recommend OSI Quad Sealant used for windows and doors. It stays soft and rubbery. Just to run a bead around the glass, until it can get fixed right. Do you think that will mess with the next person that installs it for me? Or would RTV work better?
