I just got a bottle of Pat's glue- I have suggested it a lot but never used it, so I thought I would give it a try. I talked to him on the phone about it, he insists it is as good as hot hide glue. However, the Frets site says that urea tends increase the chance of creep. I will use the Old Brown Glue for most things like gluing in linings, peghead overlay, etc, and use hot hide glue for the plates and neck joint.
