Guys, last year I participated in a 1-d match where it rained approx 3” that day. It was a struggle all day, even though I had the sunshade on, kept covers over the glass and tried to keep rifle and optic covered. Constantly blowing and drying the lenses, etc. Looks like I get to shoot in rain again this week, so need some suggestions on how to overcome this issue. I’ve heard to use Rain-X on lenses, but concerned that will interfere with coatings. What do you all use on scopes, binos, LRFs? Thanks for any info and ideas.
