Have read several post where they say you can cover with '' 100% polyester dress lining that is not the preshrunk material.

Just try to find this '' non preshrunk'' polyester. Fabric shops dont know what Iam talking about.

Thanks for any help , Glenn.

If you're covering open bays with it, that might matter. It might not matter either. From experience, I'd suggest you buy a yard of whatever they sell the most of, and test it.

If you're covering sheeting, I wouldn't hesitate a second using whatever they have. I've never once looked for "pre-shrunk" and used a bunch of polyester cloth as a lighter "glass cloth". It's magic stuff. Polyester resin, epoxy, polyurethane paints, bunch of things work very well with it. I've never had a problem using it to strengthen and reinforce. And never bothered to specially select what I was buying. OK..... I gotta admit that I actually don't usually buy the stuff. My wife does that for me, or gives me fabric she has decided she doesn't like now that she's gotten it home. Women seem to decide about half what they bought isn't what they really wanted so she's a perfect supplier of the stuff.

BTW, one of the most popular attributes of polyester is that it doesn't shrink like cotton or silk or other natural fabrics. So the advice to use "pre-shrunk polyester" is strange right off the bat.

BTW, the silk you find in those fabric shops also does pretty good for reinforcing sheeting as well.

Thanks for your reply, what Iwas told was to get was the stuff that was [ not pre shrunk] ?

Thanks Glenn.

The stuff I got from the fabric shop was called "China Silk". Had nothing to do with silk, but was 100% polyester, 1.27 oz/sq yard.

Another good source for polyester is Ceconite. Just Google "Ceconite" to find several sources and also to see just what it is. I have used it (purchased from Spruce Specialties) and it is great. As to shrinkage, it sure does shrink with heat, so be sure to have a strong structure and be able to control the heat when you go to shrink it tight. Get the lightest weight, it comes in at least three different weights and the the two heaviest are to high for most models. Note: you have to supply the adhesive, nitrate dope works well.

Glenn,

While you are looking on the Aircraft Spruce look at the Stitts fabric. Stitts has the regular fabric but they also sell a lighter fabric. The regular is about 3 OZ per squar yard and the light is 1.7 OZ per square yard. I have used it for years and it works great on larger models.

Sig Coverall is another of those fabrics.

Boy, thanks for all of the info guys this is great.

Glenn.
