For those of you who have had your windshields replaced...did the installer use adhesive on the windshield to the gasket and fit in? or did adhesive go on both gasket and frame? I had one installed by a rookie who put no adhesive on at all and did not scrape my old gasket material off. I looked in the FSM and it says adhesive from window to gasket- what is the concensus to avoid leaks/ rust?
