I went to Lowes today, and didnt find exactly what I was looking for. I did come across other materials though. One was a more flexible fiberglass, that resembled plastic in a way, seems pretty sturdy, but a bit thin. I was wondering if maybe this would be a good route, and whether or not I should probly stack another piece of it on top of it to make it stronger.
I figure I can just bolt the 2 pieces together after the cuts are made.
(Who's arm itches and thinks he may have accidentally rubbed against the the insulation fiberglass)
