I do a lot of work with wood props, reprofiling, repitching and adjusting undercamber. I am more interested in getting to the circle to check performance. I apply a quick finish with medium CA wiped on with a paper towel. I add extra coats to a single blade to bring the prop into exact balance. I consider this finish satisfactory for full normal use and life, probably as good or better than the original paint finish. When I have a very good prop that I'm completely satisfied with, I'll sand the CA down and paint the prop with black epoxy. Meanwhile, I can go from bare wood to installed, ready to fly, in about 15 minutes.
