Thanks for some clarity. On our car, of the 11 pairs of clips on the moldings, only 2 were loose when I removed the molding to paint. Upon careful inspection there was no sign of any tape ever being present. I am guessing from what has been posted that these clips were loosened from a previous windshield replacement. It was probably reassembled "non factory" and appeared to be an electronic steel to plastic weld, which failed. Who knows. I don't see any tape at the other clips so it must be under the clips and doesn't show. I am expecting my JBWeld repair to last longer than I do, but if it doesn't I'll uses some real good double sided tape next time.
