    *** What about windlace? They only seem to have the woven-finish stuff. My C23 uses windlace covered with plain white textured vinyl. Anybody found a source for that?

    All the smooth windlace is, is soft vinyl wrapped around a round foam tube and stitched. The foam tube is similar to what is used to fill large gaps, as a backing for caulking. Interior shops make their own all the time. As an owner you are allowed to "manufacture and install" upholstery material; you just need the "burn certification". There is a lot of info on that already in the archives. Just go by a decent local auto upholstery shop, ideally one that does custom work, and have them make you some matching (or near-matching) windlace. If necessary you can spray it for flame resistance, but a lot of modern auto materials already meet the specs.

    Keep in mind that the windlace is not there just to look like pretty trim. It is supposed to be soft and pliable, and to cover the door-to-frame joint with the door closed. While there is overall negative pressure in the cabin during flight, there tends to be an outflow of air around the jamb due to the relative velocity difference. This flow is supposed to pull the windlace against the gap to help seal it from drafts and noise. Once the windlace gets old and stiff, or if it is mounted incorrectly so that it cannot flex, it cannot provide this primary function. Most automobiles abandoned windlace many years ago, when car door seals were dramatically improved.

    The windlace trim as sold by RAPID consists of a single piece that is six feet long.

    *** Wow. That's less than one door's worth. And almost $30 per foot.
    This part has officially left the "screaming deal" category.
