"Buck Turgidson"
Not exactly related to wood, but I suspect there is some knowledge here. I
replaced my interior doors with solid pine. I bought some new brass-colored
Stanley hinges for the doors. They are already discoloring and even rusting
in some spots, after about 2 months.

Can I coat them with something like shellac or flat poly to arrest the
corrosion and discoloration? Should I replace them with solid brass?
They're just hinges, but it is annoying to have something look so bad so
quickly The original 40 year-old hinges didn't look as bad.


It sounds like you want the brass look so I would get the real deal.
Otherwise you could primer and paint.
