white lettering

im sorry if this has been posted 15 years ago by someone but I didnt see it.

I was wondering what the original manufacturer's used to white the engraving of for example the dwm on the toggle and the serial numbers etc.

I was also wondering if there are modern day products refinishers are using for it becuase I might like to refinish my mismatched commercial for giggles one day.
