I have a 8 yr old fish with a wood rudder. The rudder is in decent shape but the varnish on the leading edge is wearing off. I was thinking about refinishing the entire rudder but have no clue how to do this project. Does anyone have step by step instructions for a novice repair person? This would be the first time I did a marine refinish project. Also, should you use varnish or some type of epoxy if you were going to refinish a wooden rudder? Thanks..
