I have been researching suitability of coated materials for many
applications for more than ten years, and this particular problem is a
widely recognized one in the canvas industry. The specific product I was
discussing is an acrylic "canvas" called Sunbrella. Because it doesn't
fade, it is one of the most popular products in use for awnings, boat
covers, etc. (See Every canvas worker I've talked to
mentions the stretch problem with Sunbrella.

As to "all out of shape", I didn't mean to imply that the material
completely loses shape--it loses tension, which would be totally unsuitable
for a skin kayak, just as it is for the top for a vehicle used on the highway.

One reason for my interest in this list is to hear other's experiences with
particular products. What product is it you had success with?
