I rarely use a band, but in the old days when I did I always used lacquer for the finish and covered the band with it. I started that after I got out of the Army in 1969, the
uniform brass was coated in lacquer and we had to get it off so we could polish it. It was
to get that lacquer off, so I used it and I never had complaints. As a last thing, when I made NCO I bought the gold plated uniform "brass" so I did not have to spend an hour every day polishing the
brass. Did I mention I hate brass.
