That foam is the roughest I've ever seen. No telling how old it is. It has those hard chunky spots in it where it seems the machine wasn't working too good. Maybe it's a second but I'm going to use it. It is still light weight, 1 lb/sq ft.
I primered my mold so that I could check the surface. It's not commercial quality but isn't bad and will do for my cowl. I did have a problem with a few little voids in the corners on one side. The other side has nice crisp corners. I'll show some pics and explain what happened there tomorrow. It's all a learning experience and I've already learned a lot.
