ak rover said:Well up here in alaska we use this stuff as wear material on the bottoms of boats that get beached alot,. and i am going to use this stuff to as a friction meterial on the bottom of my sliders and maybe on my gas tank skid to help slide off the rocks. but even at 1/2 inch thick it will have flex to the point of pulling out of the mounting brackets. all the uses i have seen it in required a good stiff backing plate. if you use it under a rover as the fj site shows to close to a heat source and "say get hung up on a rock with a fair amount of wieght it will start to change shape and may melt to a cat converter or? and it will not return to its origanal shape. im not saying it wont work as i love this stuff but its simply not a replacement for steel or alloy but is a great compliment to both.
just my two cents
