I just went out and looked at my can and it doesn't have a number on it, it just says 3M headliner adhesive for heavy fabrics. I used it to put the headliner in the Maverick I had, best I remember, you spray on 2-3 coats on both pieces to be joined, wait about 5 minutes or a little longer to let it get tacky, then join them. You had a little time to slide it around a bit, but not over a couple of minutes, once it stuck, it was pretty much there. But, you still had to clamp it, or it would sit there and pull apart after a while. My headliner was probably heavier than hood insulation. If you laid the hood upside down it wouldn't have that gravity pull to pull it off.
