If the wood is dark (like mohogany) you'll probably get away with mixing 'dust' in with epoxy or glue. Craig did alot of work on Faith and she looks fantastic so following his lead will more than likely work. Ebb does have a point that a truely seamless option would be 'plugging' with like wood, preferably from the same piece. I found when working with lighter colored teak that mixing (teak) dust with epoxy resulted in a very dark, very conspicuous filler. I was disappointed at first but then remembered the old adage if you can't hide a seam celebrate it. Or was it perfection is the enemy of progress? Now you have three replys...
