It was Drytac "Sure Tac" IIRC. Came in a roll wound emulsion-in, single release liner. Wouldn't recommend it, but the tech support at the time suggested it was the best choice for RC papers and it did get the job done. Exceedingly aggressive, instant bond, no way to backtrack if you got a bad start, took some skill to use correctly. The overall level of difficulty with the kind of underwhelming manual roller led me to mounted canvas. Just supporting the roll required a hacked-together support bar. Before that I had used a large motorized machine with adhesive tissue supplied by the owner of the machine, who is unavailable for comment. That worked pretty good, definitely wasn't Sure Tac. Sounds like the Coda stuff is a superior choice.
