I have a new windshild (used) and need to do this. Any tips would be helpful.
I did do a search and not much helpful info.

Thanks

Rubber around the glass first, then set the lower edge in place to start. I chose to do the passenger's side bottom corner first and got it started by hand, then started to pull my rope an inch or two to get the edge of the seal over the metal lip, then seat the rubber fully by pressing on it with my thumbs and fingers, then repeat. I did about 3/4 the way across the bottom of the glass from sitting on the passenger's side of the seat, then moved over to the driver's side, went up that side, across the top, then back down the passenger's A pillar. Only had one little tiny spot on the rubber seal about an inch long that I had to fight a minute or two and other than that it was cake.

EDIT: Forgot that I used Prestone Silicone Spray Lubricant on the edge of the rubber seal going into the truck, but where I needed it most was putting the locking strip back into the channel. I would spray down about 4-6 inches of it, then put one side into the channel, then a W I D E tipped flat blade screwdriver and rubber mallet to tap in the other side of the channel cord. Really the only tedious work other than cleaning the urethane that shouldn't have been there.

I searched, asked, and found answers to the contrary on glass forums and 2 local shops that unless the seal is leaking on a full rubber surround type seal, no sealer needs to be used. The previous owner or someone working for them used urethane. That's not the correct product to use because it hardens as it dries. Correct product to improve the seal to the rubber gasket is a glazing compound 3M part number 08509 and stays soft to remain in contact with the rubber as it flexes. Other designs for urethane or butyl type seals are used when the sealer also glues the glass directly to the metal and are not to be used with the full rubber surround gaskets like ours. Around the area where I was concerned that I had a possible sealing issue, I used a silicone sealer with a temp range of -100 to 600+ continuous and flex/seal rating of 60 years.
