Details for painting rails
Dab skimpy paint on a small celled sponge. Lay a few dowels on the sponge.
Rub the dowels between the sponges to get some paint all around the dowel. Paint the Rails - mop excess paint out of the groove.
Let the glue dry.
Move the parts around often so the paint doesn't stick to the waxed paper.
Sand everything until it is smooth and the paint is transparent with lots of wood showing thru.
Assemble the Railing sets, let the glue dry, second-coat the Railing sets.
