Ken, thank you for mentioning Kapco. I actually just spoke with them today and they indicated that at one time, they did have an aqueous printable vinyl with permanent adhesive which was discontinued a year ago. As far as I can tell, they only sell aqueous printable clear films without adhesive.
Michael, thank you for mentioning the Lexjet products. They are expensive on a square footage basis compared to SIHL 3166, which I would view as a comparable product given the removable adhesive. Allsquare sells 3166 in 50"x75' for $321.00. I did not notice a width larger than 36" for the Lexjet product, and I need something as close to 44" as possible.
