New Filters from Tokina have a hydrophilic coating that prevents drops from forming. This is what I want on my dome for over/unders!!!!

Has anyone tried using Rust-Oleum's Neverwet (http://www.neverwet.com/) on a lens or dome?

The substance may form an air boundary layer and interfere with the optical property of the port. It makes the outer layer hydrophobic. Ports are designed for water contact. Several brands of these nano-coating substance is available now I have yet to see if one could work with ports.

Hydrophilic coating may work
