If you have a very steady hand there is also a paint that leaves a raised residue on the surface. I can't for the life of me remember the name of the product but we used it to make a grid board for the military on a white board.
The stuff came in little bottles with an applicator and was available in a variety of colors including black, different shades of gray and even light blue (to match graph paper).
If anyone knows what this paint is called, please chime in. It sounds like it might be the thing I need.
