Polyurethane Windshield Adhesive OK to Use in Seams?

When I finish cleaning all the cracks and seams of most of the factory body and panel sealants (and sandblast/prime), I was thinking about squirting some of the same sealant used on modern windshields in all the exposed cracks/crevices now opened up between panels and cowl. Will that seal things well? (black "Sika Titan" is what I have on hand) Thank you.
