I just pass the paper through a tray filled with the oxalic acid solution
and then hang it to dry over my sink - to catch the drips.

Unless you plan on viewing the print with back light, I would just use the
reflected light as your guide.

I normally use about 1.6-1.8ml total solution for a print this size. Rough
rule of thumb is 0.2ml/10square inches (metric: 43ml/square meter) with the
Magic Brush. More if you are using a hake brush.

Good luck!
