What's the best upholstery glue?

I've used the 3M 77 and some of my panels are already starting to come unglued. What do the pro's use so I can do this once so it will last for years? I'm planning on doing numerous interior panels with curves etc. I need something that will stand up in high temperatures. Thanks!

The place that I bought my sound deadener recommended V&S spray if you dont want to buy a spray gun. Heres the link... http://www.raamaudio.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=18&category_id=1&option=com_virtuemart&Itemid=60 Thats what im planning on using to redo my upholstery.

Thanks for the link! I don't mind a spray can, I'm just not sure if it will hold up like the stuff the pro's use? I have a paint gun so either way will work.

Youre going to need a high solids gun with a huge tip to spray any type of glue effectively. I def wouldnt recommend using a nice paint gun.  

Ya i have been told, you need a big tip and just buy a cheap gun, because you don't want to use it for paint after.

Yeah that's true I didn't plan on using it for paint after I used the glue. It's just a cheap practice gun anyways.

I've always used Weldwood DAP (http://www.yourautotrim.com/noname37.html) I get in 1 or 5 gal buckets at the local fabric store and just use a cheap Harbor Freight paint gun (http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=97855) to spray it.

Thanks for the links! I've used some of the Weldwood glue for countertops before and so far I haven't had any problems with it. I'll give the upholstery Weldwood glue a try! Thanks again! Anyone else have anything different, just let me know.

I used a 3M can one time and it worked great. Never had an issue. I can't remember what its called now though. Just make sure to get one for the temp. I used a recommended one last time and the glue couldn't handle our "hot" canadian summers. The glue let go every day while I was at work and the headliner would be touching the seats. Its fixed now though. Anyone have a good recommendation for spray can glues?
