Jim;
The prop guard leading edge tape product applied to a unprotected prop works as well as anything I have seen, 2700 RPM in heavy rain with not even a scratch. For us Southerners who have rain every day, that is a huge plus. Performance degradation is minimal from my own tests. Check it out at www.propguard.com

The two blade Warnke prop I had on the Lycoming O-290 had a urethane leading
edge that worked very well in the rain. (The rain found me three times on the
trip to Oshkosh in 1990. As I recall, it didn't even damage the finish
behind the leading edge.)
A friend had another brand 2 blade fixed pitch wood prop with the a urethane
leading edge, except the leading edge was also clear coated. In the rain, the
clear coating chipped off of the leading edge. (For a variety of reasons,
that propeller company is not in business any more. So there doesn't seem to be
a need to name names.)
My RV-3 now has wood blades on the 3 blade propeller. Each blade has a
stainless steel leading edge.
It passed the rain and ICE impact tests required for certified propellers.
It is an electric 3 blade Constant Speed propeller with wood blades from MT
Propeller.
My best time from brake release (40' MSL) to 10,000' AGL is 9 minutes 16
Seconds. That's with full fuel and me flying it. The propeller works well for
the 140 hp engine and the 300# pilot. (It would definitely climb better with a
"normal weight" pilot.)
