Re: A tip, something I discovered today.
I've considered touching up the paint. My electrical tape thing was a quick fix, I'm thinking about getting a couple of cushion clamps. one that fits the frame and one that fits the cable to hold it out away from the frame. I don't know why I didn't think of it sooner, I'm an aircraft mechanic and that's how throttle cables, mixture cables etc. are set up to keep them away from the steel tube engine mounts on a lot of light airplanes.
