the engineering problem have been solved

Sometimes, we need stiffness more than toughness. I'd much rather see a full set of numbers on this stuff.

line-x bed liner

That's not the numbers he asked for.

No comment on the Coroplast piece in the video I posted that was curved across the corrugations?

He did that by heating the inside with a heat gun where he wanted the bend.

There ya go. Heat gun > bed liner. And cheaper, too.

Anybody actually analyze the failures for their cause? Like web failure or skin buckling, or skin seperation??? Bedliner will stiffen the skin, but if the failure is the web, or skin between the webs, it wouldn't help. I myself shove music wire into the holes every so often to make it linearly stronger but that does nothing to preventing collapse parallel to the webs.

Just to follow up, I did end up using the Corrugated FRP Wall Panel to make my front undertray. It is quite strong and I'm happy with the result.
It's pretty light and strong. This is a 4' long level and a full 5qt oil jug.
