Sure Shine is more than a metal polish! It is specially formulated as a one-step application that cleans, polishes, and protects most metals and fiberglass and plexi-glass products with an effective coating that is designed to last 3 to 6 months. It contains no harsh acids, caustics, or abrasives, so it is safe on most materials. To use, apply a small amount of polish to the area that needs cleaning.
