69 Camaro 1/4 in buytle tape and back fill with glue is the old way of doing things.
1 I wouldn't use 3M products that glue is way to thin no viscosity to it.
2 never put glue rite over paint primer, Most paint primer is PORUS and most glue is moisture cured.
3 Paint the pinch weld or at least cut in the jambs and pinchweld with the paint
Then use you urethane primer on the paint, most urethane primer have a etching chemical in it to adhere to the bonding surface.
4 you mentioned on you glass didn't have the frit band. that is because they used buytle tape back then and rubber gaskets.
so to use urethane wet scrub the outer area of windshield at least 3/4 in of edge all the way around then if you glue has a activator use that then a black primer over your 3/4 wet scrubbed edges
I think you would be better off just going to the 3M website for product information.
True, Yankee go home. Enough of the name calling, the Guru of Glass just schooled you, then offered to help you. Who is the better man now? And you are old if you still use or own a pipe knife. It's 2014 not 1974
And please, use proper grammar and spell check. It doesn't have to be perfect but good grief! Better to be quiet and have people think you're an idiot than to open your mouth and remove all doubt.
O GEE, Quotith Not All Ye Sinners. Save a tree guys!!!!!!!
I don't totally agree but I have to say you're spelling and grammar was much improved. Thank you. Remember, others read these posts and form an opinion of us, good or bad.
Ohhhhh, now someone is backpedaling lol I have only been in the industry 8 years and I know Essex has not made urethane in over 10 years. It's called Dow. Also if you use the 3M primer as directed it will not peel off and crack as you state. If you do not use black primer it will fail from UV exposure. So here you are again giving bad advice. Why don't you just tell him to unroll some butyl and let it ride old timer. And Smiley is right, much better but still a total of 17 grammar mistakes. Just write what you want to say, copy it and paste it in Microsoft Word then copy that and put it on here. Not making fun of anyone because mine is bad also so that's how I do it. Jamie trained me, he once told me he that most people with a lot of years under their belt are set in the old ways of doing things, apparently he is right. You can keep your "decades" of experience, if I need a tape kit or a 55 Chevrolet roped in I'll call you. Now apologize to everyone and let's move on.
The only PTI I remember was butyl tape and liquid butyl. Never liked it as well as 3M Window-Weld. How many remember cutting out butyl set ws on a 90 degree day. The banana knife got kind of messy on Torino's and LTD. Then they started putting that @#%^ urethane on across the bottom! Memory Lane!!
I am sorry but I have to chime in, GM used poly sulfide not butyl like Ford with a dam material to install windshields and back glasses before urethane. I have been in the industry over 30 years and work on allot of older cars and have never seen a stock GM windshield with butyl ...I could be wrong but I haven't seen it
