I am a band director and I have a student who's parent would like to polish up their Conn Cornet. It has no lacquer left and has been through a fire (years ago), so it is quite "ugly" to look at. I think it's fine, but parents know best, right?
What is the best polish for the horn? It is a 1971(ish) Conn Cornet, Director I believe. They would like to keep it on the cheap and easy side, but I let them know there were no promises on the easy part.
