thanks for the reply dhbailey. you gave me some useful information. I understand about the unlacqered brass. I have a baritone that's unlacqered. I polish it with acetone sometimes. I wont try lacquering my horns, I'll try it on some brass and metal first to see how it works. If I dont like it I'll give it to the shop. I cant find the Nikolas lacquer on ferree's tools. Is there a search on his site? If not what is the link for the lacquer?
