I used 3M 08693 Auto Glass Urethane Windshield Adhesive, here is the link from Amazon
https://www.amazon.com/3M-08693-Uret...window+sealant
Check with local mom and pop auto glass installers, because they buy in bulk, I talked to my glass guy, and basically about 1/3 of Amazon price. I used two tubes, one per side, I had the hood on and opening and closing nicely, didn't have motor or trans in, so, I got inside engine bay, started filling the channel up with adhesive, and let it partially cure. while it was still soft, I used several new razor blades to trim the excess off, and left it undisturbed for several days to fully cure.
not a real good picture, but the black lines on the ribs are the trimmed sealer. hope this helps
