Let me throw this out for comment:

My wood prop has rain-induced pits in the outer 3 to 4 inches of the fiberglass leading edge.  (Something about going to Florida.................)

Previous encounters of the aerial aqua variety have simply stripped the paint off.  This time I have actual pitting.

SOMEONE suggested a thin coating of JB Weld (thinned with alcohol????), then sand and paint.

Anyone have a better idea?
