This Loctite pl premium construction adhesive in the 28 oz tube is most likely out dated. We have used at least a dozen tubes in the last couple of months and it still glues very well. I know because I had to remove a small section. The stamped date on the bottom is in one of the pictures for those who can read it. One tube for $6 or 12 for $50. For those interested in a larger quantity please ask how much or make an offer. I go to Bozeman/Belgrade every week or two and I could bring some with me to those interested. Livingston could also be arranged. A couple of tubes had a few occasional runs but were still usable and the rest worked like new.
