'No, you missed the point. As stated earlier, it matters not what
system...
Polyfiber or dope or 3 step urethane or waterborne.....it is during
heat tautening, before ANY top coats/sealers applied. The currently
available 101 (3.4oz)
material has a great propesity toward assymetrical
shrinkage....vastly
more aggressive across the roll than lengthwise. Predicting it to
allow
for this while at the same time not too slack to avoid ballooning is
nigh on impossible (certainly beyond 1st timers). And once again,
2.7oz
SEEMS to be less susceptible to this condition. It has nothing to due
with the fabric being "stuck" to underlying structure. I am making a
distinction of a great difference in shrinkage behavior of 3.4oz and
2.7oz. You will notice the far heavier promotion of the 2.7oz over
the
3.4oz material by the various suppliers. It is an interesting
experiment to use the same people, tools, techniques, topcoats,
adhesives, preparation, manuals, and enviroment to cover one wing in
3.4oz and the other in 2.7oz. Try it once and see how different the
wing looks. I have.....one wing 3 times!!

away from any place it has unintentionally adhered. It is a simple
matter of inspecting the job closely after the brush coat of Poly-
Brush
has dried, and lifting the troughs by sticking a needle in the fabric
and prying it up. The hole the needle will make will self-heal with a
little heat, which will soften the Poly-Brush and allow the fibers to
move back into alignment.
