Sealing top of windshield (Re: oozing windshield sealant)



Ford windshields circa 1980 are also glued in. Have cured leak on a
Lincoln and my truck same way, although I used basic silicone from a
gun (that stuff doesn't fool around -- clean up excess while it's
still wet). No problems after 3 years.

Question for Rick: "It, however, hasn't been exposed to rain, so my
success or failure is theoretical at this point. I hope never 
to test it." Your D doesn't come out in inclement weather? Kind of
defeats purpose of our "rustproof" little cars...
