I removed(purposely) a trace on a circuit board.
Should I paint the exposed board with nail polish?
Should I just leave it?
I'm thinking if I don't seal it, the board could absorb moisture and become conductive.
But is nail polish ok to use?
Is there something I should use instead?
Thank you

By far the most common material used in circuit boards is glass reinforced epoxy laminate. I have not seen this material absorb water under "normal" working conditions.
So, I'd let it be . . .

Is the rest of the board painted? If not, then what is the difference?
I would never worry about the binders used with fiberglass. Paper-base "can" absorb moisture but millions of pocket radios got along without special treatment. They die of floods or damp sheds.
