My  interest is in a coating that protect the copper from oxidation with age.

Before any other "chemistry" to the board, TIN-PLATE the copper (just a  
"hot-dip" for 20 min. operation).  Makes it nicer to solder, and protects  the 
copper from "turning".  There is a dry "crunchy" chemical called  "Tinnit" from 
Kepro, I think it is.  Haven't used it in SO long, I forget,  now.  Dissolve, 
use heated.  Has a definite "shelf-life" and "goes  bad" if not used up within 
a few weeks (days?).
