For etching, Nital 4% is probably the best choice. It gives higher contrast than Ferric Chloride, is less messy (as it does not stain yellow everything that comes into contact with) and is less prone to rusting.
However, Ferric Chloride is not that bad and it can be successfully used instead of Nital. I used both.[/QUOTE]
