To say the least, I am not happy to hear of your experience, Wynne, but my
kayak is now two years old, sits outside (under cover) and so far has shown
no signs of any stretch. I also can't imagine anyone selling material as
suitable for awnings if goes all out of shape in a couple of years. The
product I used could not be made to stretch with ant application of heat.
You could melt the PVC off the fabric but still no stretch. Might you have
gotten a PVC coated nylon fabric? This type of fabric should be more prone
to the performance you describe.
