Back Window Installation

[41Fordor]

I've been putting off roping in my back window in my 54 Customline sedan after finding all the chrome trim and polishing it. The Carpenter directions say to install it dry. But the 54 shop manual says to put sealant ("rubber cement") between the glass and gasket.

There was no sealant between the old gasket and body when I removed it. And with the light green cloth headliner, that black butyl sealant would get everywhere.

What does everyone else do? Thanks!
