It was black. I don't know if it was panelbond. I spoke with the service manager when I was in there Sat. and he said he would find out for me. It almost looked like a black epoxy/resin but had a mesh texture you could see in/under it. Like I said in my other post, it looked pretty nifty and definitely sturdied up the metal tabs. The LP tank covers are VERY fragile so they need something keep them from "cracking up"
