Kester Techform TC 564-1 water soluble mask is a good product. Cures at
room temp in minutes, and can be soldered when not completely "dry". It's
the best we have tried, and has a one year shelf like at room temp.

None. Dissolves completely in 140 F waterwash, no residual visible, cleaned
boards will pass SEC testing.
