Potatos to Pledge.

I have yet to find a really good "sheeting action" material that you can coat the front of a port with in order to provide dripless over/ under shots. I use Pledge furnature polish and have no ill affects on the port. It works OK but not the best. I have also heard that rubbing a raw potato on there work well too in a pinch. Anyone have the silver bullet? You "still" guys, feel free to jump in here too.

p.s. I got the term "sheeting action" from a dishwasher detergent commercial.

I usually get that 'action' after a hot curry...

Although I heard the same about potatoes...

I have been using Rain-X for years. It lasts for several dives.

Thank you for your e-mail inquiry. The Rain-X original glass treatment contains a very high concentration of alcohol, which makes it incompatible to Polycarbonate and Plexiglas surfaces. It will etch the surface making it extremely hard to see through.

Simply spit on your lens, rub a little, rinse and shoot. Repeat as necessary.

This method uses biodegradable ingredients that will not harm your lens - and you can put the potatoes to better use

Even Rain-X thinks that's a bad idea:

It may etch plastic, which I haven't seen, but it should be OK for glass.
