Last week our air conditioning broke down and the temperature in the house got to 84 degrees or so. As a result, I now have a new repair project. A bass I recently acquired popped the seam where the bottom of the back meets the ribs. I don't know what this bass has been glued with- there was gooey glue oozing from old cracks in the back and the glue in the seam was very stringy and gummy. I'm planning to reglue it myself, I have spool clamps, etc. I have some granular hide glue that's probably 5 or 6 years old. I realize once it's been dissolved and heated it's only good for a day or so. Does it deteriorate in granular form? Should I toss this stuff and buy fresh glue? Where's a good source to buy quality glue? Thanks.
