Using West System G/Flex epoxy, it would be possible to shealth an HDPE rudder in fiberglass, if the HDPE were first flame treated. I have glued blocks of flame treated HDPE directly to fiberglass with G/Flex, and the joint seemed as strong as the materials themselves. Tyler

I don't know if anyone is using it, but fiberglass reinforced nylon injection molding is probably going to be a lot lot stronger for relatively long thin foil shaped sections. I'm not sure of the details but I think that is one flavor of RIM (resin injection molding) technology. It is used for high strength high quality lower price point (than pure glass or carbon fiber) paddle blades (kayak/canoe). I've never seen anyone use HDPE for that and I can't imagine it would work well.
