My dry mount tissue for many years has been Bienfang BufferMount, which sets upon cooling. It produced a good bond between a fiber-based print and archival mat board. I had previously tried their ColorMount product, which melts at a lower temperature and is evidently designed for RC paper, but it did not produce a good bond with fiber-based paper. Im about to mount a solo show and want to re-order BufferMount and discovered that it is no longer manufactured. What dry mount product(s) do you currently use, and are you happy with them?
