Anyone done this, or know anyone who might have What
did you use? Acids, electro-etch? Formulas, proportions, temperature,
masking liquid or material, time frame?
I have a large high-relief engraving job to do on a high priced

the way to remove the larger areas of background and save me some
time doing it by hand?
