I just received my T4X. It has very light corrosion on the chassis. I have seen photos of others that have very bad corrosion. Are there any solutions to this problem? When I was a scuba diver 50 years ago we used white vinegar to remove the corrosion from the brass parts of our equipment. Bob Macklin K5MYJ Seattle, Wa. "Real Radios Glow In The Dark"
