anybody fix a sagging headliner? just picked up a 40 and part of the headliner in the back looks like it has pulled away from the fiberglass. wondering if there was a spray adhesive I could get up in there and reattach.

I did not have any luck with 3M Super 77. I tried it on a cloth headliner in a passenger car- held for a week or so until the weather got hot. I tried recleaning the roof and reapplying but had the same results
I did a complete resto on my 77 and put in a brand new headliner on clean glass with 3M super 77. Held for a couple months, but as soon as the weather got hot it started letting go. Sucked because I did a pretty good job installing it with the cap off and upside down, it was easy to do then. http://www.crustycruisers.com/ps152.jpg
Now I had to try and fix it after my resto was done with the top on. Hard to do with the roll bar in the way and working upside down. I had to peel back some of the edges to get to the areas where it had totally let loose. Divided each area into 1/4's and applied Weldwood contact cement on the liner and top with a foam brush. You don't need a lot, let it tack up for about 10 minutes and then stick the together. Make sure you get it right the first time, because this stuff is strong.
5 months later and no problems......should have used it the first time, live and learn I guess.

I also had poor luck with the 3M adhesive on my '82 FJ40. I used a new headliner with the roof off and clean. It lasted about 1 year but the headliner almost completely fell off last week after having left the truck parked for 3 weeks in my garage while on vac. I think I will try the contact cement that Matt used...just the input I needed...
Kinda sucks to read this thread a week after I just did what you guys said didn't work! Had the fiberglass cap off, used 3M 77 stuff and it turned out OK but it sounds like it isn't going to last long. My question for you is this, should I just wait for it to completely sag and fall off (assuming this is going to happen) or will I ruin it by pulling it off the top and reglueing did you guys have to buy a new headliner and start over or what did you do? Thanks
Green thing,
I would wait for as much as possible to fall down on it's own. Mine started falling in the middle and kinda spread from there. The weight of the headliner kinda does the work once it starts, parking it outside in the sun should help it fall a little quicker. I finished my resto in April, was fine until about the begine of June. That's when I started driving it more and it was getting hot outside (Minnesota, hot) It may not fall everywhere, but probably 90% of it will. The little bit that did still hold was around some of the edges. The stuff that did hold I had to slowly and carefully pull off. It wasn't too bad, but a little bit of the foam on the backside will probably remain on the fiberglass cap where the 3M adhesive is still trying to hold, just pull slowly.
The Weldwood contact cement works very well. The reason I used it is because I have used it on my Jet skis for new foot pads, and that's what the manufacture recomended. One of my skis has had the pad on for almost 10 years now using that stuff and it's been in lots of sun and water and has never let go.
Don't get to carried away with it on the headliner foam. Make sure you brush a good coat on, but not to much. It will begin to soak into the headliner foam and when you apply it to the roof, it may look a little lumpy if you put to much on, so less is more in this particuliar application. Applying it to the glass cap is fairly straight forward, it can't soak in and you can see what you have applied. Wait about 10 min. so it can tack up on both surfaces before you stick them together.
It still sucks, working inside the cruiser upside down is WAY more of a pain in the ass than working on it with to top off. I just tried to make sure it stayed centered, that's why I did it in 1/4 sections. Make sure you get it right the first time, Weldwood will not let go once it is stuck. Mine still looks pretty good, but it was absolutely perfect the first time I did it......prior to it falling down of course.
