Many years ago I used cellulose paint as resist, thinned somewhat and
painted on the copper with s fine paintbrush. I used a centre punch to
mark the holes through the pattern drawn on graph paper. I then put a
small blob of paint on the punch marks and joined them up. The paint was
very effective as a resist, and was easy to remove.
