ACM board much better than coroplast

[freebeard]

Thanks for asking. I like materials science (flip-flop paints, quantum well catalysts and all that). Since I posted I've been following up leads from the Alumacorr vs. Poly-metal link.

Alumacorr is apparently more fragile. Right now, it looks like Grimco - Substrates: Max-Metal, MAX-metal HD. It's like Polymetal, but has 30mm aluminum skins.

Their Grimco - Substrates: Max-Metal, MAX-metal is reportedly less expensive than Polymetal.

They have other interesting products: Grimco - Substrates: Environmentally Friendly Substrates, Enviroboard MR is apparently water-resistant corrugated cardboard.

As for what would I do with it? If I could afford mass quantities:

Brushed aluminum on the outside, white on the inside. Edges are glued and riveted into aluminum H-channel.

Else boat-tails, bellypans and fenderskirts.

maybe the op could reply to his own thread?
