wings too?
If I like the feel, yes. I hope to cover this wing front section to rear section. Seemed at the spar.

The extra cost isn't going to be a deal breaker for those of us interested in part 103, but the weight increase could be. An ounce/yd is 15 pounds, just for the fabric on a part 103 120ft^2 wing.

Distressing news for sure!

Does Sig sell their 1.2 oz in bulk? If not where do they source theirs?
They sell it in Big sizes
SIG KOVERALL
SIG MANUFACTURING
SIGKV003

There are probably several mills that make these polyester fabrics. There is no need to get the fabric through Sig for an experimental aircraft or anything that flies.

The obvious common sense approach is to simply find out what the Sig (or Poly-Fiber, or Ceconite, etc.) fabric technical specifications are, and then go to the fabric mills and ask for a fabric that meets specification XYZ.

No mention whatsoever of model airplanes, full-size airplanes, boats, tractors, parachutes, or umbrellas. Unless Sig is actually willing to sell you the large rolls they buy, and you want to help Sig make a little profit (they deserve it), they don't need to be involved or put at risk in any way.

Wicks has uncertified 1.87 oz fabric for \$8.40/yd.
The OP was looking for 1.8oz fabric. Surely the .07oz/yd delta isn’t a deal breaker?
