I'm looking for a varnish/paint/conformal coating that has good UV durability and low water absorption. This is for an outdoor use, and it's capacitive sensor so I need to keep the thickness down, so using glass or even tape would cut down on the performance. Any advice, or what products to avoid, are welcome.
