Richard,

We've use this company's paint pens.  Only a solvent will remove them.
Not a very fine point but we tried lots of alternatives and they seemed the best.

Subject: [TN] White Paint Pens

The white paint pens we've been using to mark on PWB solder mask have been discontinued.  These pens required only a room temperature solvent evaporation cure.  
We've tried a couple of alternatives, but these have washed off with our wash chemistry.  I'm looking for alternatives.  

To maintain non-commercial forum, please send any specific recommendations to me offline.
