Painting or sealing the inside of a wooden stand?

[LostMind]

I was the guy wearing the grey baseball hat

I have some minor issues in my stand cuz of the salt spray from my sump. But the tank and stand have only been up for maybe 9 months so I am definitely concerned about it.

On my next stand, I will definitely be using some waterproof paint to seal the insides. Personally, I am going to give it at least a double coat. But then again, maybe I am just a bit paranoid of having my stand collapse and send tons of saltwater pouring thru my new house!
