The Origami Forum

I was wondering if any of you guys use any resin material so to preserve your folds over the years.
I saw models folded from paper hard as a rock, and I was wondering what kind of material is used.
If any of you have any idea, I would be glad to hear

Thanks

MC finished models can be very hard, but still very susceptible to moisture. So finishing with acrylic sealer is an approach many use.
