To water/splash proof your ESC or any electronics buy a spray can of Conformal Silicone for electronics.
Take your case off and apply two coats to the circuit board per side and let it dry for a day. This is specially formulated for electronics and will protect them from moisture.

Do not use potting epoxy or similar because it shrinks and can damage the circuit board.

This silicone is what I used many times to test electronics around water and its been put into production by many ESC vendors.
