yup i just plasti-dip mine. hold it by the wire and dip it until about 1 inch of the wire is covered also. hang it to dry and then just trim lightly around the drive to slip the horn on. use a dab of waterproof grease under the horn so that it stays sealed, you dont want to use an rtv here because it hardens and as soon as the horn moves it will break the seal, heavy grease will stay fluid and keep it sealed.
