Last week I asked about coating brass after polishing. Not much in
the way of replies, but I thought I'd try powder coating (clear). It
worked --- it's still fun to put such a hard, shiny coat on things
without painting --- but the polished brass darkened a bit during the
baking process. Not bad, but it's just a little darker than freshly
polished brass.
Growing up as a musician playing brass instruments, I remember taking
care not to spoil the "lacquer" on the instruments. Whatever it was,
it lasted a very long time (I had one trumpet that was over 50 years
old and still had a fine shine under the clear coating). ANYBODY know
what this was? Can't get spray cans of clear lacquer at Wal-Mart
anymore (they're all enamels of some sort); the auto paint suppliers
here no longer sell any lacquers either - forced to only sell stuff
with low VOC numbers.
