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?).
