I'm getting ready to spruce up my AR-4X grilles. One of the grills is broken- judging by the thickness of the piece (not very) and the materials (it appears to be masonite, but I could be wrong) I would imagine it happens a lot. I kinda wanted to retain as much of the original speaker as possible, but have resigned myself to the possibility I may have to cut new panels. But I want to at least try to salvage them. Has anyone tried this, and can they recommend a decent glue for the purpose? The thoughts off the top of my head are epoxy and gorilla glue.
