I understand that you've had good results, but please be aware that a board
I made 2 days ago is now more tarnished than some of your 25-year-old
boards.  I suspect it has much to do with climate and the particular alloy
used as "copper" cladding.  the other possible variable is the etching
process used.  I used a positive art photo etching process on my now
tarnished boards.

It almost always rains here, in Vancouver.  No matter what anyone does, it
rains when they wash their cars.
