Worked perfectly

Used this to install the rear seat/trunk divider in my '68. The screws are self tapping, the right length and have a very flat panhead so they won't interfere with the back seat. I pre-drilled a couple screw holes for alignment, then applied the sealer and installed permanently with all the screws. The tube of caulk has enough product to seal the panel, note that it will go on white but will become clear once cured. If you apply in a cold garage like I did, it will take a while for it to fully cure.
