3M 77 spray adhesive was sold to me for use to attach a new headliner in my pickup truck. It was easy to use and seemed to adhere the new headliner quite well. However, within about 2 years the adhesive has failed, and the headliner is again sagging. I suspect it failed due to the heat that can result from the sun on the truck roof. Admittedly, I am located in Hawaii so have a more intense sun than most, but the truck is garaged and only rarely is out in direct sun for hours at a time. Regardless, it proved unsuitable for that use.For less demanding projects where heat is not an issue, this probably is a fine spray adhesive, although it seems a bit expensive for a general purpose adhesive.
