Hello Sergio,

The basic solution I would recommend is to apply a barrier layer and then
write the number on that layer with ink. This way, the number can be
corrected or removed if necessary, but it can't just fall off.

A conservation-grade barrier layer would be Paraloid B-72 (dissolved in
acetone. About 5-10% should do). Apply it with a brush, wait a few minutes,
then write the number. Most "permanent" markers do fade sometime, so we use
the old way: black china ink or white ink (whatever is most visible on the
surface) applied with a pen nib.

With some practice, this is easy to do even on small bits.

Hope this helps,
