A few years ago I got some really large heat shrink from Gary. It was 9" wide and great for wrapping battery packs. It is almost more of a plastic than a rubber like the regular heat shrink for wires. Does anyone have any idea where I could get more of this? Or an idea of what it would be called that I can find it? I've checked electronics stores, hobby stores, Grainger, no one even knows what I'm talking about.
It is not a sheet, it is a very flat tube, I tried taking a pic of the tube, but it was hard to see when it was black on black.
