Ive got about an ounce of Mr Zip extra fine dry graphite in a squeeze
bottle that might last the rest of my life, but it's messy. Even masking
tape on the bottom of the hinge doesn't stop it from migrating during
application.

Noticed art supply graphite crayons that might be easier to apply. Would
they be good candidates for hinge lubrication?

Next time I try this I may just wet some of the powder to spread with a
flux brush.
