Any collective word on treating windscreens with water-repellent?
I've treated my BAS and other outdoor windscreens with water-repellent silicone spray intended for fabric in the past. It doesn't make them heavy rain-proof, but light sprinkles bounce off and mist beads on the surface instead of soaking in, and if they do get damp they are easier to squeeze dry with a paper towel and don't remain wet. I usually treat them and let them dry a day or so before use, just to avoid any potential problem of damp silicone somehow effecting the mic capsules. Not sure if doing that is important or not, but better safe than sorry.
Probably a good idea for treating furries as well, and may possibly mitigate some tangling and matting in fur prone to that.
Ideally I'd like an improved all-weather BAS with a sonically transparent waterproof membrane under a surface layer of thin hydrophobic foam or short fuzz. The outer layer serving to damp

the impact of raindrops like the old towel atop the umbrella technique.
