So, in the 1988 GM service manual, concerning the "vent glass" (sunroof) weatherstrip, on page 8J-6, it specifies applying a "bead of adhesive between outboard periphery of weatherstrip and body opening to prevent water seepage". Okay. Typical of GM service manuals, it neglects to specify what type adhesive. Is it similar to "super weatherstrip adhesive" (yellow) or is it a silicone base sealant (caulking)? When I removed the previous (OEM) weatherstrip, it appeared to be a clear silicone. Any suggestions?

I've always used a small amount of the yellow stuff. I think it 's more to hold the strip in place than prevent actual leaks since that's the job of the rubber.

Anything I might say is probably worth what you paid for it, so treat it accordingly!

Removed track, then sealed the track to the roof, then the seal to the track as per bulletin instructions. Lower corners of figure 3. View A and Section A-A

Never use "caulking" or a silicone caulking blend.These products have the consistancy of clay, and wont hold up. 100% silicone would work good, and comes in black,clear,white and a few other colors.Look closely,some products look more like Roofers Tar. I beleve the last tube I baught was at Home Depo, GE Brand Premium Waterproof Silicone, Window,Door,Attic,basement water proof,flexible,shrink and crack proof. Wear rubber gloves when working with these producks.
