Interesting never had that issue with my Vforce lenses. I don't know of lenses having a "outside protective coating", mine only have the anti-fog on the inside. For dual panes it's all in how you do it. I run water over the outside with out letting it get on the edges. I've not had a dual pane get compromised that way. I carry a 1 gallon pump sprayer with water when I go to the field. I use that to clean paint off the lens. I then shake it dry and use a microfiber cloth to get off any streaks. I also carry several lenses, just in case.
