This has always been a problem area. Is there a "headliner glue" out there that works the best? I find I can get the headliner in place wrinkle free, but unless I put some chunks of windlace to hold it and let it dry over the next day or two, it will tend to fall off. I was using 3m trim adhesive, then started using weather strip ahesive with better results, but would much rather use the correct stuff. Chris
