Hi All
Just in case some of you got any of those horns Mike Caldwell sold a while back I wanted to share this. Mine were very tarnished and on one the face was deeply gouged in several places.
I would recommend a Dremel tool with rubbing compound to get rid of the tarnish. After that, simply drag it in the same direction face down repeatedly on a belt sander. I would not attempt running the belt sander or you could take off to much aluminum very quickly.
As you can see these look pretty close to factory new condition. Note on the back horn the gouge close to the opening. I would have loved to get it out but would have to take off several mils more of the face.
I should have taken a before picture. This is a vast improvement.
Hope this helps someone.
Ken
