Polyfiber polytak vs Stewarts systems glue

[Dennis Flamini]

i glued 3 sample 1" strips of fabric and pull tested them at 90 degrees per Polyfiber's STC. The samples cured 24hrs at 65 degrees.
The first sample was Stewart's blue glue at approx. 3.5#
The next was dried out Polytak that was thinned with MEK and acetone not too good at approx.1.8# The last was new Polytak at approx. 3#, which was better than specs at 42oz.
