Hey Steve, I have a can of Hartzell Propeller Epoxy Paint right here in my hangar - Louise had it, and repainted her prop a while back - I'd rather have a good coat of paint on it than the typical eroded leading edge that attracts corrosion. I agree with you - for an experimental, you shouldn't have any regulatory issues. I also know that for certified airplanes/props, there ARE paperwork issues. We didn't do a strip, just a light sanding and paint over the old stuff, and it looks like new - makes mine look ratty....
