While Sharpie is a permanent marker that can be used on a variety of surfaces, it is not recommended for use on golf balls. The ink in Sharpie markers is designed to be quick-drying and fade-resistant, but it is not necessarily waterproof. When exposed to moisture, the ink can run or bleed, ruining the appearance of the golf ball. In addition, the chemicals in Sharpie ink can interact with the cover of the golf ball, affecting its trajectory and spin. For these reasons, it is best to avoid using Sharpie on golf balls. There are many other options available that are specifically designed for marking golf balls, and these products will provide superior results.
