Nanotherm's latest pastes had a few revisions... although I'd hardly call them revisions... more like scrapping the whole thing and restarting, but keeping the name. In the first "revision" of my review, I was not impressed with the Nanotherm's new silver pastes. The XTC was runny, hard to apply, a pain-in-the-ass to get off, and electrically conductive when dry. The EXP fared much better, but it was also electrically conductive.
