What Coating is This?

A simple explanation, with emphasis on simple, between conformal coats and potting is:
Conformal coat is a thin, painted-on-the-board compound that protects against humidity and dust.
Potting submerges the board deeply into a substance, and protects against more harmful chemicals and provides additional mechanical protection.

As other posters have mentioned, non-acetic RTV coats cure by absorbing humidity from the atmosphere. The problem with a deep submerged conformal coat, is that the upper surface develops a "skin" that will prevent the deeper materials from completely curing.
For that reason, potting compounds are usually two-part.

Thanks, not trying to beat a dead horse. Just not familiar with the standard ways of doing things like this and what will be sufficient. Not looking to spend money, but want to do things the right way.
