well i lightly sanded it. i tried stazon, distress ink (the worst, it just beaded up on the stamp), color box. the best ink i tried was a cheap cheap craft ink from michaels, the problem is the color i had was a bright teal. not what i was looking for. i used versa mark embossing ink and black embossing powder, eh.
i think this might be where i say, "pick one thing you cant do well and .... dont do that thing" frustrating.
