I knew you guys would want something that's reuseable yet works for sealing.
Since the stuff is oil based it will repel water and not get affected by it.

A 1 lb brick of it was $3.57 plus tax when I got it from Hobby Lobby and in my case that makes it cost effective to say the least, esp with it being reuseable.

Again, I don't know exactly how well it would work with a LN2 setup since you guys have to use a heatgun or hairdryer sometimes.
It's low melting point temp of 165f may or may not be a prob there but for DICE it works very well. If it works with LN2, that would be a great thing to know since I know stuff used for prepping does cost $$ and this will help to cut your costs for benching and nowadays anything on that part helps.

Be sure though you use it, know that it will not absorb water at all.
I will make a "Dam" around the edges of the prepped area to keep water from running off elsewhere whenever water appears and soak up what does appear with paper towels or something. I've had ponding in this area before and the stuff didn't let it get through to the board itself so it will protect in that way at least. Still I do remove the water in case I have a spot that wasn't sealed properly to be safe.
Be sure around the CPU area (Under the pot itself) that you don't have a cavity of space it could collect water in - The last DICE session I did showed that water will appear under the pot even though I had the edges of the pot sealed off but even then it didn't hurt anything, proving to me it does seal well. I suspect it ran down inside the pot's insulation wrap and got in that way so that's something I'll need to work on for my setup.

Nothing like removing the pot and seeing a literal pond of water under there around the CPU itself BUT nothing was hurt by this.
