In the 1970's we used to use clear nail varnish to protect the lettering on the Eddystone boxes used for our lab lashups, written in black Rotring drawing ink with Rotring drafting pens. I have used the same type of varnish on the Letraset we used for the panel of the mixer console that my son made for his GCSE technology project. The sheets of Letraset I bought in the late 1960's still work OK.
