Subject: Re: [TN] Conformal Coat Over No-Clean Flux
25 or so years ago, Wally's (Rubin) Wonder Flux (Multicore Xersin),
which was claimed to be inert after soldering, had a CC variant that
could be applied over the residues. I never tested it, mainly because
WWF was not really the best flux in the world for oxidised leads.
Theooretically, it sounds as if it may do the job.
