Thanks for that link Glowplug! It reinforces what I suspected. The colored fabrics are about twice the weight of the plastic films even before adding paint trim and clear coating. Something I didn't realize is that "natural" fabrics are a bit lighter than the "colored" fabrics(7.5 vs. 9to13). Would this be negated by a need to fill the weave before painting?

Campy, it sounds like the colored Coverite is heavier than the colored Solartex.
