I purchased this a long with Meguiar's M17 to clear up some scratched and foggy Jeep Wrangler windows of mine. It did a great job coupled with the Craftsman random orbit buffer I bought locally. Not only did it reduce the appearance of smaller scratches it nearly cleared up the fog left by other cleaning products and from natural weathering of the clear plastic. I feel that after a few more applications that it will more than likely return my windows to a near new state.
