I have some material similar to that. Got some disposable hospital gowns from a recent visit, stuff is tough and light.

It's been a while since I read through this thread, but I thought the appeal to use the coffee filters material was its tendency to be more controllable in expanding and shrinkage during application and drying.

I agree with that. Just got back from the shop, finished covering ailerons and half of the rudder. Coffee filters are very forgiving, you have quite a bit of time to do fine positioning and they don't tear unless you want to. I find that instead of a credit card I can use my finger to smooth out wrinkles and remove air bubbles. Instead of a spray bottle I'm using a sponge to wet the filters.

You mean like Esaki ? Which tears as easily as kleenex ??
Hell Coffee filters are only marginally tougher. Ease of application is one thing.. but resistance to Butterfly impacts must be worth something too ??

GPW may be referring to the type they use in their folding laterns, fairly light but durable.

Paper with fine threads??

I'd be very interested if it as light as newspaper but tougher to tear.

Oriental rice paper with silk strands.

I played around with some product that is used to keep roots out of a septic drain field. It is available in large rolls and is made to bury underground. It is like a very thin coffee filter. I covered a bead foam wing that I cut with a hot wire. I used the water based poly and it made a very strong wing.

I used it to cover a bead foam wing that I cut with a hot wire for a test. I used water based poly to soak the paper. It made the wing very strong.

If anyone would like to experiment with it, I can send you a letter sized sheet in an envelope.

It would be valuable to compare the coffee filters and other materials bend strength against newspaper.
See https://www.rcgroups.com/forums/show...6&postcount=90 for the test conditions used for the newspaper bend tests.
