For years I was able to buy a 4 oz plastic bottle with a twist lock cap that was a perfect size for administering glue to miters. The twist lock top was the best I had used to put just the right amount of glue on the miter and at the same time keep the dispenser free of dried glue. These bottles are no longer available because hair color now comes pre-mixed-that was their primary use. After extensive inquiries I have located a source for them and am wondering if framers might be interested in buying them if I made them available. I have never seen anything close that is available from usual framing supplier sources. If I get some encouragement I will pursue this beyond my individual needs.
