How to minimize water on the housing glass
 

I shoot fly fishing videos, and a lot of times I have the desire to transition a shot from below water to above water, but usually only get a second or so after I pull the camera out of the water before the housing's glass has the water run off and leaves drops of water across the face of the glass. Is there something I can use that will allow the water to sheet off properly without leaving unsightly drops?

Mate, This will sound strange but I've heard surf photographers lick their lenses, I'm serious.... I've never tried it as most of my water video / stills are taken underwater.

just use RainX on it, buy at any auto parts store

If you can pack one in use a small aquarium just big enough to put the camera in and sink it below the surface of the water.
Keeps your camera dry and gives you the transition shots of below & above without a special housing and safely keeps your equipment dry also.

When I was recording underwater shots for my Chinook salmon filmed, I spread shaving cream on the inside of the underwater lens housing and than would wipe it off with a lens cleaning cloth, this kept it from fogging up. About every 2 hours I would reapply. This may work for you by applying on both sides.

I have had the same problem and I think too, that the nano spray for spraying on the auto glass will do the job - I just have not tried it yet...

Pulp of an apple rubbed on the lens. It does wash off after a while but works great. Try it.

The best thing I find is spit... spit on the port / lick it then it will be fine for a minute or so.

RainX works ok but I reckon spit does just as good a job.
