Yep, I sanded down the plank and at the same time I was lacquering a piece of wood so I thought hmmm, that might look OK on the plank,
Thanks Beaky on the circuit board lacquer. I bought a tin of this stuff from Jaycar a while back but then I got to thinking, if I lacquer the circuit board, and then I find I have stuffed up somewhere it would make it hard to re-solder any components.
When you mentioned solder through lacquer I grabbed the tin and read the de******ion and sure enough it is rated as solder through.
I never knew there was such a thing.

Cheers
