I could not resist on replying to this! I prefer the colophony/resin
disolved in the nitrocelulose thinner as it dries faster than disolved in
alcohol (any kind of - aethanol or methanol or isoprophyl).
As for now, I've produced (for my needs - this evening) 20 PCBs that will
last at least 10 years, and the only coating on the copper side is the
colophonium/resin.
