I have never had any PVC blades. But I've seen many people posting here about experimenting with them and so thought about improvements.

Besides machining the leading edge and the trailing edge, maybe some filling with fiberglass resin or other plastic the thickest point of the airfoil would make the airfoil to look perfectly like the K2 airfoil?

Maybe good paint would make them to last in the sunshine?
