Exactly. I've used the same ply for years with no problems. The only thing I used for the first time was the Weber set S1 adhesive..never again.
Think you should go back to shop you bought it from and speak to manager,try and come to a comprise say 50 50 to cost of rectifying and never use it again. If manager not willing to then ask when the next time the area manager will be around or ask for his contact details and see what he says?You take a few up first to check for that.
