Graziano SAG 12S dials

Hi,

Over the last year I have reconditioned and repaired an old Graziano 12S lathe.

Part of the recondition was to clean and blacken the dials. They were rusty and you could
barely see the numbers.

I cleaned them and blacken the marking... Today I see that part of the carriage dial has some
rust again.

Anyone triad spraying translucent spray over the dials ?

I spryed it all with protective oil but it still rusted again, any ideas what to do.


Thanks,
Noam.
