There are tons out there. Like MG potting compound which you can get on Amazon in small tubes

Did it on an AV1 Hud S. Never flooded again

Yeah friend I've only used some gel stuff a bit sticky that stays gel a bit like that reusable adhesive but more fluid

no hardening

SO YOU CAN GET IN THERE AGAIN

I've had good luck with food grade silicone. Seals it up but still allows disassembly.

Is that what you used on seal O2 cells/Molex?

I can't say to do this as I have only personally used it half dozen times but all with great success. I have been potting stuff in hot glue. Yes, the kind your mother uses for scrapbooking. It seems to seal very well and can be peeled back out at a later date.
I don't have any professional testing or data to backup how and where it will fail, but it has been working really well for me for a few years in fresh water above 300'.

I used that on my first build

My second rebuild I used loctite e-60 nc.

My last one

E-60 nc.

The cost is similar but you have to buy the dispenser for the loctite. Peanuts really.
