My coating method is rather similar in that I making multiple passes
in order to even out the coating. This includes passes on the
horizontal, vertical and diagonal of the coating surface. However, I
coat with either a Hake brush or the Richeson "magic brush". Both are
much softer and abrade the paper less than common foam brushes.
