Homebrew PCBs

I've been following this subject for a few days now and I guess it's 
time I add a note about my touch up solution. I use a product that I 
bought at a local A C Moore craft store. It's called Painters 
calligraphy, made by Hunt Corp in Statesville, SC. It has a felt tip 
and works quite well, although it is a little slow drying. Blowing on 
it helps. Mine is black, but it probably comes in other colors too.
