I highly recommend a product called <Woodtite>. There is no mixing, it never grows old, you can clean it up with a rag, there are no odors, it drys as hard as a rock, it has the consistenancy of water so it will run down little holes with the help of a pin. It is gap filling but it is not a glue. Its cheap. It is also a good idea to turn the bridge pin in the hole with a pair of vise grips so as to present the string with a unimpaired new surface.
