This has been bugging me and maybe someone out there has the answer. I can't seem to get the strip of headliner material on the inside bottom of the back window on my '66 beetle to stay glued-down. I have the same problem on the wife's '74 with her section of carpet. I've tried all sorts of "professional" grade contact cements and all seem to fail from the heat of the sun. Does anybody have a good choice /brand of adhesive to recommend. Neither car has the material tucked under the window rubber as per factory, so unfortunately, it's all about the glue. Thanks in advance !!

Neighbor and old time mechanic recommended this for my headliner project (in progress). I'm just using it now, no report on longevity.

Also I've heard good things about this, not tried though:

In my opinion this is the best overall interior glue around. I have used it on everything. Expensive, but awesome.

I live in the hot deserts of Southern California... Temps get 110+.

I prefer 3M Super77 and have never had a problem... Simple, cheap and you can get it almost anywhere.

Just read and USE the directions. Spray both areas that need to be glued. Wait till it gets tacky... attach. You will even have a bit of time to move into the correct position.

Other glues can be way too strong IMO.

Say you want to remove that carpet or headliner someday... Your going to have to scrape that crap off with a bulldozer...

you may have to remove most all the old glue before using the new better glue. good glue over bad glue may still lead to failure. bad glue being the weak link

good luck

Contact cement is the only way the two listed above are great follow instructions after done keep out of direct sun light for that day then u are good to go. Both surfaces get glue let dry a few minutes till when touched doesn't leave any glue on your finger and doesn't string off your finger. Once u put pressure on instilling don't pull it back up make sure everything is lined up ahead of time.
A simple spray gun does a great job spraying the contact cement don't use the water base wilwood with green label only the solvent base red label. Or the professional grade in gallon from above no spray can glues.

X2 on the weldwood industrial HHR contact adhesive. I have used this for numerous interior projects and the bond only improves over time, you will need a dedicated spray gun though...
