Ah yes, brass pox (bronze pox?). That's why I don't like lacquer. Clear packaging tape works well and is not as ugly as electrical tape. The thinner the better to fit the compound curve of the bell. You can also use poor man's lacquer: nail polish. It should be removed and reapplied regularly.

He expected the owners of his horns to have them relacquered on a regular basis. The lacquer on the Conn is a baked-on acrylic finish that is much harder and more durable but which, when it starts to wear, causes deep pits to form. Use a handguard and/or small pieces of electrical tape at wear points to protect your instrument.
