Luke, I have no idea how I originally stripped the old paint since I've had that horn button hanging up in the garage "as is" for a few years. I do plan to strip another crusty one in a few days and will report back. Will say if there's small amounts of rust in the chromed raised areas, that will add another challenge which would need attention before I paint.
