thanks for the link. I gave it a go yesterday before i had to leave for a BBQ, i used just cold rolled steel and stainless 304. It worked pretty well quite the pattern for the first time id say. It didnt seem to want to etch too well though. I tried using pcb etcher. Are people diluting this etching solvent or just strait solution? I left it in for about 15 min and the contrast was great, however after a quick rinse with water the black rubbed off. any suggestions?
