Dennis,

Are we talking about Black & White or Brown & White? It's my experience that Brown & White requires longer etching times.

The RS solution does contain a small amount of HCL. I dilute it one more time than what you listed, down to around 3-4%.

Regards
Ken

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
