If the can hasn’t been used in a while or is new, it’s important to
clear the nozzle by turning the can upside down and spraying it for a
few seconds before applying it to your piece. Not doing so can create
a fogged coating pieces that have to be cleaned and re-lacquered
I’ve used it to coat the insides of lockets that have been patinated
and also on etched copper/silver bi-metal. It really deepens the
oxidized copper and heightens the contrast between the two metals.
The wear on bracelets and rings, however, makes the lacquer rub off
in some areas and not others, leaving an unattractive mottled effect.
