I use Corrosion-X on the ones I have sprayed.  I think I picked it up from Amazon a few years ago.  On some well-protected boards I haven't even bothered.

What do you mean by waterproofing?  Are these boards going to he directly exposed to the weather or just condensation.

I'll second this one.  Corrosion-X is great stuff.  I only use it for connections.  Mostly the Cat-5 DMX and LOR wires and sockets.  It leaves a thin film that protects.  I also saw another brand recommended from another site, and I tried it last year.  It is called MAX Professional Electronics Lubricant.  It also worked well.  It could be a similar formulation to the Corrosion-X.  Both lubricate the metal parts, promote the connectivity and both are safe with plastic (such as the connector bodies, etc).

If it puts down a thin film, wouldn't that cause issues with the connectors?

The formulation is designed to promote connectivity.

Much like WD-40, it is thin and gets out of the way when metal meets metal.  The problem is that if the item gets rained on, it also tends to be washed off.

I've been doing this for 9 years and never used a coating.  Insurance is great, but there is a risk / reward consideration that goes along with it.  It is a personal preference.

I haven't used any coatings on my boards in 6 years, but this year I bought a bottle of Corrosion X for guns. I called the company that makes the stuff and the lady said it's essentially the same thing (electrically safe), and it comes in an applicator bottle with a fine tip rather than a sloppy spray bottle/can.

I'm not interested in drenching my boards. I just want to use a bit in my "waterproof" connectors which aren't always waterproof, you know.
