This stuff is a lifesaver!, I was having lizard problems with PC boards on 2 Mitsubishi minisplits at the house, (apparently a common issue) but not anymore, we would have one fail every few months, 3 boards last year and none of the service companies knew what to recommend, they'll just sell me a new board and installation, it has been over a year since I spoke to Brian and he explained how to apply the coating, the last service guy that came out to do maintenance said he found a live lizard on the board just hanging out and never shorted out, I have saved Thousands and I have now applied it to the electronics in the outdoor TV, Pool heater and pool pump. I bit expensive but 32 bucks a can compared to $600 every time the board got fried on that stupid Mitsubishi AC unit, I'm money ahead avoiding almost 2k of potential repairs
