[sdiy] Acrylic coating on PCBs

[Happy Harry]

Why are you worried about copper oxides... they will form their own
protective coating... the copper will not oxidize all the way through,
just on the surface. If you need to solder later, a little scratching
with an x-acto knife will reveal bare copper again.
