I don't know about urethane, but I know foam tape won't work! That's what my installer used, and they had to go back and buy the clips and a new trim piece. $30 of clips is better than $300 of trim. :-(Is it really worthwhile to replace these expensive clips for the mouldings on each side of the windshield?
Is it possible to get a good installation result with just gluing them with eurethane at each fastening point?
