  • Searching for info on finish of Warnke constant pitch prop

    I am interested in any information on the finishing materials used in the manufacture of the Warnke wooden propellers.We have one that is aproximately 15 to 20 years old and in need of a slight refinishing job on the trailing edges and a small loss of finish on one leading edge. It has a black material that looks like a carbon composite product on one side and what appears to be a white composite lamination on the other face. The black material doesn't appear to have any varnish or whatever finish was used. Any info would be appreciated as they are no longer manufactured.
