Anyone have idea what would be the best option for protective coat on HI-Z areas? Attached image of the Fet in Rode NT1. Hard to see, but it's covered with clear coat.
I would think something like this should do the job: http://www.farnell.com/datasheets/3157684.pdf
I'm not sure if that was the exact type, but I recall using something very similar a few years ago, on PCBs that were to be installed outdoors....
