Years ago, I used to use an electroless Tin plating solution
based on Stannous Chloride, Sodium Hydroxide, and Sodium Cyanide.
It produced a beautiful plating, but was a bit of a pain to work
with. If you left it exposed to air, it would oxidize fairly
quickly. If you splashed in a bit of acid, it would evolve
Cynaide gas, which would rapidly kill everyone in the room.
If you didn't have the temperature quite right, it wouldn't
give you a good plating.

I've since given up on it, and usually just solder the boards
now.
