Greetings All, I just noticed www.mouser-dot-com has a product called 'Final-L-Kote AR'. It states, 'provides insulation against high voltage arcing and corona shorts'. Has anybody tried this stuff? Is it worthwhile? Are there other similar products? Is it a good idea to spray the back side of a MMC board with this stuff? How about the top windings of a secondary? Many Thanks, Bill Parn
