Is their any pens that wright on plaster and paint? - Model Railroader Magazine

For the life of me, i can't find any pens that have the capabilty of writing on dark color acrylic paints over plaster .   I've purtchased paint pens from hobby lobby, walmart and micheals with no success.  

I've tried using paint with fine brush ( masking tape between) but the paint somehow seeps thru underneath  and it doesnt create a fine line. 

Any suggestions ?
