I am soon to commission the making of a brushed stainless steel equation of
time plaque to go with a sundial. Experience of two plaques in recent years tell
me that the black paint (or whatever) used to in-fill the etchings does not last
more than a couple of years or so. Has anyone got a recipe for an improved
paint, or an alternative way of guaranteeing permanent contrast between etching
and background surface?
