The old wooden Sensinich props were typically lightly sanded and varnished with a decent spar varnish as needed. If they were kept inside, the finish lasted for decades. If they sat out in the weather, they typically needed to be touched up annually.
Other props like Peformance Props and Warnke used Durathane polyurethane finish which is really tough and lasts nearly forever. -Jeff Scott Los Alamos, NM Subject: Re: KR> Sterba prop I have refinished several of his props the exact way after asking him years ago. It is very easy and works good. One issue I have though with the Helmsman varnish is that you really need to keep your prop covered if you keep your plane out in the sun. I had one on my Midget Mustang and the varnish was deteriorated after less than a year. I have wondered what Sensenich and other prop makers use for varnish since other planes sit out much longer before having issues.

This is for all Sterba prop owners and wood props in general. Non Steba owners check with your manufacturer. correspondence below; _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
