Review on ZetexPlus Welding Brazing Plumbers Pad by Jerry Frey

I used this to avoid catching fire on the fiberglass tub and bolts when replacing the shower valve. If you hit it directly with propane it will start to "melt". So if you can't avoid a direct explosion with a flare, this is a one-time thing. I bought two and folded them in half so I had four levels of protection. When I was done with the solder, the 1st layer was completely burned, the 2nd layer was charred black, the 3rd and 4th layers were hot to the touch but not damaged or hot enough to damage the bath. It worked. for what I needed, but it's by no means perfect. I would still recommend it, just be aware of its limitations. It is rated for 2000 degrees, propane burner burns around 3600 degrees.
