What a get product! I wish I would have known about this years ago! Thanks!

Good product, saved my ass everytime soldering against wood

Seriously, they literally catch on fire. I just bought a five pack a week ago. The first one I used was serving as a shield to protect some rubber bushings while using a torch to heat a stubborn drive shaft bolt on my truck.After a few seconds the flame looked odd. I turned off the torch to see this thing on fire - literally aflame! The flame from this shield quickly spread to some grease that’s normally found on a fifteen year old truck - exactly the kind of situation why you use these shields. I had to use a fire extinguisher I had setting nearby “just in case” to put out the fire this shield caused.After putting out the fire and settling down a bit, I took a second one and put a torch to it to see how it would react. Within a few seconds it also caught on fire.I don’t recommend these things if you need them to serve as anything other than kindling. Craziness!!
