It's a clear liquid that, when brushed or poured over copper, deposits a layer of silvery metal (tin I assume) on the surface of the copper...nearly instantaneously. It just seems to plate out of solution onto the copper. It's most interesting to watch. It was sold with the printed circuit board fabrication materials, obviously intended for post-etching tinning of the remaining copper. I don't quite recall what it was called; it's still packed up from my move. But it was really neat stuff. -Dave PS - Happy holidays to all my fellow classiccmp'ers!!
