hi,
i have thought of simply dipping a newly etched board (drilled as well) in a clear wood varnish simply to prevent oxidation (its quite cheaper compared to other commercially available pcb-specific products)
the problem is, if i dip the whole board in varnish (w/o components) the the pads would be covered with varnish. if those pads were already covered, then i still need to scrape the varnish off so that i can solder components. isn't it would be tedious for a 100+ hole board to scrape off varnish before soldering?
is there a way for me have the pads covered first, then easily remove the covering after applying the varnish?
