Where to place the sealing bead on conventional windshield rubber?

Ha! I've replaced literally hundreds with gasket and without like the GM that's held and sealed with the black bead roll sealant. Lemmie tell you, not one single time have I EVER gotten a gasketed window to seal without sealer.

I like using 3M clear automotive window sealer. I cut the tip small, and after I install the window and get the gasket all worked around even good, before I put the lock strip in, I insert the tip between the outside of the gasket and the pinch weld and go all the way around with the sealant. Then install the lockstrip and call it done. Sometimes after you install the lockstrip, a little sealant will push out around the gasket. Be ready with some rags to wipe it off before it sets up.
