This is the conformal coating that I have used to protect my drones for 5 years. My quads end up in the water nearly every week...and we flew through a bando in the rain yesterday...Weather you end up hitting a droplet of dew on a blade of grass or you sink your quad in the Abyss, Conformal Coating is the way to protect your electronics from water damage.
MG Chemicals is great for every board on your quad, but dont paint it in buttons, switches, or connectors that you plan to use. It's a light duty coating, which makes it easy to rework through it, just solder and go without needing to remove the coating to repair your quads.
