I just used Dawn dish soap and water in a spray bottle. Probably around a 3 to 1 ratio. 3 being the water of coarse. I didn't use any sealant. My friend who works for Safelite Auto glass advised that since the 3M non hardening isn't available anymore to just see what it does first and if need be I can address it then. Says he puts them in a lot without sealant with out issues. Especially if the pinch weld is in good shape. So that's what I did. Time will tell I guess.
