I am about to re-install the windshields (front and rear) on my 59 Silver Hawk. I removed the old rubber and found this grey/green putty between the seal and the body.It is also between the seal and the glass. A quick check of the shop manual and it states "Lay a bead of soft bedding compound around the corners and up the sides of the mounting flange." What exactly was this "soft bedding compound" and can I still buy this? I checked with our local automotive supply and all they have is urethane. I am not sure if this is what I should use. What do you experts think?

Do not use urethane. Use 3M 08509 Bedding and Glazing Compound. It is made for sealing windshield rubber and the car body. I believe you will find it much better and easier than trying to use 3M strip caulk or butyl tape. You can buy it from Summit Racing if not available locally. Two tubes should be enough. I think Bob Andrews has some pictures of a windshield install using it but I cannot find the thread.Last edited by 5brown1; 09-07-2013, 05:07 PM.Comment

I get 8509 bedding and glazing compound from NAPA. O'Reillys has it too for $16 a tube. Takes about a tube for a windshield.
Use the rope trick but cross it at the top instead of the bottom. Place the windshield exactly where you want it to land. Do not try and get a head start by placing the rubber over the pinchweld because it is not going to slide down... the rope will take care of pulling it over the pinchweld. My book says 3 men... I've done it solo but two people are plenty.
Place the 8509 in the glass channel and a second bead in front of the pinchweld... not on the pinchweld. Pull the rope slowly and let it draw the rubber over the pinchweld... alternating left rope and right rope.
My first attempt after 4 tries and 8509 everywhere, I called my glassman thinking he lived 20 miles away and I'd see him tomorrow... He was in town waiting for a part at NAPA.... be right there! Oh*(&^*&( I didn't want him to see the mess I'd made! Grabbed the Goof Off and met him with a smile and a clean Champ. Took him/us 15 minutes! That first time before I called "uncle", I made all the above mistakes... didn't begin with the glass squarely in front of its destination... placed it on the pinchweld instead of in front to start... put the 8509 on the pinchweld instead of in front of it.... crossed the rope at the bottom instead of the top.
I've done 4 since without a problem using the above techniques. Don't be intimidated by this project... just follow the script.Comment

Sorry I didn't remember you did the blog Dick. I used it to do my windows. Thanks for posting.
Sure would be nice to change the title of this thread so it will come up in searches about windshield installationComment

To your original question..... 8509 is soft and remains relatively soft for ever. Urethane on the other hand sets up in hours and securely glues the windshield to the rest of the body. The common design when Studebakers were built required the glass to float free as the body twisted and bent thus soft bedding compound was called for. Today's design considers the windshield to be a structural component that also most stay intact under impact to keep the occupants inside so the hard setting urethane makes sense for today's vehicles.Originally posted by RDWEAVER View Post
So 8509.Comment

Thanks, this place is the best. I guess I should have checked here first, the guy at the auto parts store probably had the tube of this stuff in stock but did not know it and I did not know the number but now I do..... thanks again.Comment

The number on the tube is 08509. I don't know if that 0 will make a difference in a part search - but it might.Comment
