Solvite 'Ready To Use' Wallpaper Adhesive. (Woodhall Park SN2)
About 3/4 tub left. Not sure how long it's been sitting in the garage shelf, but there's nothing on the tub to indicate that it has a 'Use By' date once opened . . . just says to fit lid tightly, avoid extreme temperatures and protect from frost, all of which have been done.
