Nail polish works just as well.


White nail polish makes an excellent slippage mark for indicator coverglasses
where range marks are required. We used it in the USAF along with clear nail
polish to extend the life of the rangemarks themselves.

Glyptol is a material used in that same fashion on electronic components
like pots. Nail polish was commonly used as a substitute and may have
been the same thing.

Essentially it is brittle lacquer in a bright color making it easy to
see when it has been applied and making it obvious if the component
on which it was applied has been adjusted.
