Water proofing a sensored esc?

[Rumpelhardt]

I've never attempted this before. I have a Hobbywing Justock ESC that I am thinking about using for a while in my next project which looks like it might be a Deadbolt. I would like to try waterproofing this esc because I already have it and it's not a very expensive one if I screw it up. I have watched a couple video's on doing this and it doesn't look particularly hard but I was wondering if the process basically the same for most esc's and would this esc work ok in an otherwise stock Deadbolt that will see mods added over time.
