Installed glass and tried two different gaskets both have pucker on lower corners. I used the lesser of the two evils but still disappointed. Any Tips?

precision gaskets.
First one from Partsmix.
Second from local glass shop

Me to, seems like NOS would be the way to go. But then it is 50 year old rubber. Next time I go to GYC I will ask what they use.
 
Get a bottle of liquid rubber, fill the gasket pocket and paint on edge of glass. Put on glass and top too glass. Let set 30 mins then reinstall. This is not Urethane its called Liquid rubber used for cars during the 60's and 70's.

You need the liquid "buytl Rubber" fill gasket with it. Then pain on 1/2 of glass around edge but tape glass so not too messy. Let fgasket sit a while, slide over glass. Tehn tape inplace. Allow Liquid rubber to "set" then mount gasket on glass tape gasket in place around gasket, letting liquid rubber to ooze out on to glass. Once its set on you can install and pucker is going to be better.

72golddustermike, I had this issue with my 66 Satellite. The gasket would conform on the sheet metal side but would pucker on the under side of the glass, in the lower corner. I determined that the gasket had excess material on the flange that goes under the glass (needed to be shrunk if it was a metal part). We carefully cut a small pie out of the flange with a razor blade where the pucker was most pronounced in both corners. We started small and increased the size of the pie until the flange would lay flat. If you are careful with the cut it is almost invisible. We did not glue the flap back together as we only cut it down to the start of the glass channel and sealing was not effected. If you wish to glue the flap o-ring glue will work, which I believe is just super glue. Hope this helps, Brian.

Not understanding where to make cut any pics?

72golddustermike, sorry no pics and I don't think that I can take any on my car that would helpful with the glass installed. I will try to give a better explanation. the bottom of the windshield gasket has a channel that slips over the edge of the glass. The channel is approximately the same on both sides of the glass but the interior side has added length to create a flap to close out the instrument panel fence line screws. I believe if you look at the gasket you will see where the glass channel ends and the close out flap continues on (they are on different angles). That "flap" portion of the gasket between where the inside of the glass channel ends and the interior end of the flap is where the pie cut needs to be. Install the gasket in the windshield opening and gently push down on the top of the flap and tape it in a position that looks like it would fit the glass. Work evenly on both sides of the pucker toward the center, the flap will show you where the pie cut(s) needs to be made. Hope this helps, Brian.
