what sealant did the factory use?

hey guys, when i had my body stripped to metal and after paint i missed two spots when sealing the body back up. i thought it was my rear glass leaking but it turns out its body seams leaking at the bottom left and right corners of the rear glass where the quarter panels and the panel in between the quarters in front of trunk lid come together. pinch weld area under rear glass rubber in the bottom corners. i now have to pull the back glass out and seal it up there.

does anyone know what was used to seal in these areas from the factory? so i don't buy the wrong stuff.
