I like
Plasti-dip and tulip paint if it's a brushable liquid you want.
I have had both down to 666 feet in the ocean and no failures on hydrophones or electrical connections.
No failures on auto parts.
Plastic-dip lasted 7 years that I know of with just slight chalking while sitting in the lake havasu/Mojave/Mohave sun, unsheltered.
(This is why I tested flex-seal. A comparison)
