I picked up a big rock chip in the windshield on a gravel road north of Taos. Its time for a new windshield. The tech tip does not even mention sealant and some others such as Brothers youtube also do not mention sealant. It rains in Oklahoma and I need sealant. I just want to do it correctly. When I installed the windshield years ago I may have used too much sealant or the wrong kind because the windshield did not really drop fully into position but it never leaked.
1. What sealant do those of you that have done this successfully use? 3M 8509 and CRLaurence 7708 have been suggested.
2. Do you apply the sealant to the weather strip or to the cab?
3. The FAM page indicates three steps and #3 says apply sealant "to the flat of the windshield opening rabbet along the entire length of the pillar side...". Can anyone clarify that statement as to just where to place the sealant? It seems to me that is the same as step #2 in the FAM.
Sounds like it just means more sealant around the sides. I have a 55.2 service manual and it uses the same words. Not really helpful.

Wow! It's so symmetrical and dead center to boot! Was it thrown up by a truck or something? Must have been a pretty big stone.

Couldn't have been centered better if I had measured it. Yes, a dual wheel flat bed pickup I met and he threw up a rock that appeared about the size of a golf ball. Fortunately no paint or sheet metal damage, only the windshield.
It's been a couple years since I retired from the glass business, so I'm not 100% up on the currently available products, but personally I think I'd prefer the CRL caulk. I would run about a 1/4" bead around the perimeter of the gasket where it contacts the body, after you insert the rope. Try to stay away from the rope and lip or you'll have a mess! Kerosene or similar solvents work well to clean up any ooze outs. John
New Classic parts of America windshield is installed. I used a Steele gasket and CRlaurence 7708 sealant. Applied sealant to the gasket, I did not add extra on the sides. The only problem was the lower corners have a bigger gap than I like, see the photo. The glass is all the way in at the top and the bottom, so I don't think I could have done much different to close that gap. Also had trouble getting the stainless trim to fit properly on the lower corners when I inserted it into the gasket. I'm thinking possibly the glass is not quite shaped right? At any rate I will add a little sealant material around the lower corners and call it good.
