2016I did my first PCB Oct. 9th using this technique w/ ferric chloride. Then I coated the copper with TInnit dissolved in water. It turned out great. Then I realized I forgot to print the pads on this thru-hole board. So I did it again, after rerouting the tracks.I also got this technique from pulsar fx. I didn't find your write-up here until Oct. 30th.
P.S. If you etch w/ ferric chloride, don't forget to wear clothes too ugly to shop in at Walmart, work atop newspapers atop plastic sheeting, and wear chemical safety goggles.
