It was OK for about two years, but during one particularly hot summer, the glue started to soften and the edges of the upholstery started lifting off. the lifting and peeling at the edges got so bad eventually that I just pulled off the console from the car out of frustration as even touching up with more 3M77 was not working and was just causing a mess. I think it is after that that I decided never to use 3M77 for any kind of heavy duty bonding. I also noticed the architexctural models I built in school where I and my classmates used 3M77 to bond plastic and paper textured finishes to building model walls, eventually started to fall/peel apart just sitting on a shelf in my apartment for a few years. They were always indoors, but I think the very dry heat in my apartment eventually affected the spray-on glue's bond.
