Clear sprays (Krylon Clear etc.) were once popular during the thru 
hole days when there were well defined component and solder sides to a 
board. These days, most of us just prevent the copper from tarnishing 
any which way we can but this is usually done before soldering (Liquid 
tin, Tinit, solder paste etc.).
