Paul, we use to purchase blanks (so long ago I don't even remember from who, Brodrick racing - or something like that) and carve our own props for pylon racing. We used CA to coat the wood props when we were finished carving on them because it was quick, readiably available, and easy. I'm sure that laquer finish would be fine too, since most of the wood props come that way anyways. I also believe that the thin CA was lighter, and would penetrate into the wood better over the laquer. This way, when you did your final sanding right after you coated it with thin CA, you would hopefully still have some protection from the elements (especially for those guys that fly in the rain LOL) after thelast time that you balance it. As 3Dreaming indicated earlier, there is allot of balancing to be done. Balance between each step. I just don't have the time anymore to mess with it.
