I went to our local car paint and body shop supplier and found a 21ft roll of adhesive backed mylar trim molding 1/8 wide. I cut it to length and carefully fit it into the grooves that exist between the various parts. It fits in those grooves perfectly and so far is holding well in out AZ heat. I was really surprised what a difference it made. Total cost $21 with about 10ft left. I figured that GM parts wouldn't sell those separately since the supplier ships the pads with the inserts already installed.
