Gasoline will effect our coating by making the affected area softer. Avoid heavy impact and power washing in these softer areas because you could damage them. As gasoline evaporates rather quickly, a small spill will only soften the top layer of the coating which will re-harden as the gasoline dissipates. If you have a larger spill and gasoline sits on the coating for a couple of days, the entire coating will be soft . Carefully remove the gasoline , the coating will harden again but it will take more time. If the softened coating is damaged, remove the affected area, de-grease the area and re-apply coating. Our coating adheres well to itself, even after many years , as long as the original application is properly cleaned.
