Bought some of this after a recommendation from a friend, have only used a small amount so far, but will only be buying this stuff form now on. No its not the cheapest, but the little I have used has been left out in the sun in my truck on 90+ degree days, the old stuff I pulled off kept sliding off, getting sticky in the heat and sun. This lasted through late august early September, and now winter to this point. Has been out in the garage or in the truck the whole time, through cold and heat still looks as good as it did the day I put it on.
