So, this happened. I noticed the knot was wobbly. A little tug and it came right out. It looks like the knot was resting on a partial ledge. Any suggestions for re-knotting? I'm thinking: Dremel out the "ledge" that remains; repaint the inside; and build up the inside with epoxy (and possibly dimes) to the appropriate height. How's that sound? What type of paint should I use? Thanks.
