I have been turning a lot of spalted maple in the past year and some of the material was riddled with worm holes, tunnels or however you wish to label it. I have used the 5 minute epoxy from Lowes to dye and fill the voids. As many as I have I need to find a more economical source for epoxy. Someone with more experience with using epoxy may point me in the right direction. Would prefer a quick setting material that has a long shelf life before mixing. Any guidance is appreciated.
