Sealing for printed circuit boards

++++

I have a printed cicuit board that is letting moisture penetrate the protective coating, how can I prevent this.

Spray lacquer, give it a few coats and you should be set, I would worry more about WHY moisture is getting into your circuit boards rather than how to stop it.
