Originally designed for manufacturers of mobile homes, campers and RVs, the material stays soft and pliable, so it installs easily and conforms well to corners. It comes rolled on specially treated release paper for easy handling, and is easy to clean up.

Can be applied in temperatures between -20°F to 180°F. Best results if applied at room temperature on dry materials. One year shelf life and two year application warranty.
