My second 1965 Dodge Dart.
Went to Dave's Auto Parts and got a little bottle of Chrome Polish from Turtle Wax, and polished the horn ring. I am a novice at this but thought I got an ok result. Not so easy to polish over pitting. It is what it is, and I have to live with it for now. Not going to have it drilled and soldered and rechromed at this point.
