nice work!
Such a nice and clean looking pcb at a glance - it is amazing the nasties that lurk if you don't know where to look.
I have bought some clear nail polish - I am trying to find a compatible dye to put a few drops in so I can overcoat bare tracks to prevent new corrosion and restore the green tint. So far I can tell you humbrol enamel is not compatible :)
Cheers
