Is there anything that can harden thin layers of cardboard, inside AND out, permanently? Answered

This is for a sculpture project where I am building sculptures out of cardboard.

Any sort of glue will do this to some extent. Mod podge, epoxy, wheatpaste, regular glue, etc.

Is regular glue another name for, "white glue", or PVA?

https://en.wikipedia.org/wiki/Polyvinyl_acetate

I tried asking Google(r) images about, "regular glue", and I think most of the search results look like some kind of PVA, but I still don't know for sure if people really use that phrase, "regular glue", in real life English.

Wires through the corrugations (isn't that how they're called?)

Polyester resin, as rickharris suggested, but it'll probably be pretty expensive...

Acrylic paint will do just fine too.
Just make sure it is not water based as it takes forever to dry.
Also gives a nice surface finnish if a stiff brush is used to get the last kinks out of the cardboard while applyng the paint.

Polyester resin - it will soak into the card and then harden.
