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.
