All of us that pick am old hone now and then find flaws that we wish we could fix or at least strengthen and shore up. I ran into a product lately that I thought might be of interest here. It is an acrylic that remains liquid until you hit it with a UV light. The light hardens it in seconds to a clear hard plastic. There are several brands. This is just the one I happened to pick up. I have a nice coticule that had a small chip and a gap where is was glued to the BBW. I dripped the plastic into the gap and hit it with the light and could build it up to get the corner back in good shape.
