When drawing on a surfboard, it's best to use waterproof and fade-resistant pens, such as Sharpie paint markers or Posca paint pens. These pens provide vibrant colors and are designed to withstand water exposure and UV light. Additionally, acrylic paint markers can also be a good option, offering a range of colors and good adherence to the board's surface. Always ensure the surfboard is clean and dry before starting your artwork for the best results.
