Duster windshield removal/replacement

Professor Fate said
Honestly, you should not need any sealants on a gasketed windshield. The rubber gasket itself is the seal.
Sealants are for flush mount windshields.

The rubber is the seal, if using any goo then something is wrong. As above potentially pitted metal or reused seal. Worse case there is a rust hole somewhere

I know that this is an old thread but....
Have either of you two ever read the windshield installation procedure as outlined in the service manuals? Sealant is clearly called for in both the "fence" channel and the groove the glass fits into.
