water drops on your lens

[gibson1525]

after coming up from the dive i always like to snap a few shots of the boat, shore, etc. while still in the water, but i always have a few water drops that i can't get off the lens. anyone know of something i can put on the outside of the lens to get the water to 'bead' off so i can get some good post dive surface pics? mayve a rainx type product?

I use a substance called RainX that I get at the local auto supply store; one caveat is that I don't know how well this works on polycarbonate housings as opposed to the glass lens front on my Top Dawg housing.

Don't use RainX on acrylic ports. It will etch them. More than you want to know about it here.

Spit or baby shampoo work on acrylic. In a pinch, dunk your camera right before you take the picture; usualy better than big drops from a partially dry dome.
