I'm using it to make a bullet smoker smoking blanket and it works just fine. It’s just that the freight is very expensive. For 4,000 square meters of fabric, it cost 830 US dollars by air.

This is very effective for partially covering a thick piece of material during preheating and welding with 9018. It's relatively light. The silver silicone coating does an excellent job of catching weld spatter. It looks durable, but time will tell. I'm thankful there's no fibreglass coming off everywhere like a cheap blanket.
