Hi Marc. I had several emails with Ed about props he built for me before he retired. These quotes are from those emails. I hope they help you.
* The urethane leading edge on this new prop * Wood Propeller Installation and Maintenance NOTE: During Installation, please treat the Urethane Leading Edge carefully, it takes a few weeks to fully cure! … The urethane leading edge should prove very durable, however, high power run-ups over dirt or gravel will definitely pull debris up into the bade. It is best to pull the power back a bit when flying in rain to reduce the tip speed and erosion forces on the blade. Repairs to the urethane can be made with epoxy resin although it will not be as strong as the original material. Small quantities of the original urethane material are available from Sterba Props.
