Some protection will be smart.In searching for a vendor of Liquid-Tin I ran across
this waterproofing spray:

Since I live in the RustBelt and know what oxidized
copper looks like, I wonder if I should use this on
my PCB to keep the copper from contacting moist air?
No, tin will just change the type of oxide. Tin oxidizes too.
My PCB will be used outside in a plastic box. The
plastic box will be waterproof, but not airtight.
I am guessing the Liquid Tin and leaded solder ap-
plied to the traces will prevent oxidation. I just
Just about any clear acrylic will adhere to clean copper and FR4 and it's variants.want to know if anybody has had experience with this
product or, if my thinking is wrong.
Has anybody used this product on a copper PCB used
outdoors? If yes, would you recommend it? Or
would something cheaper like this

work just as well?
Tin plate enhances solderability, and oxidized tin is generally easier to clean and make solderable.
