Honestly, not much! First of all, it’s always a good idea to give your board a quick rinse after paddling (especially if you’ve been paddling in saltwater conditions). Secondly, don’t leave your board sitting out in the hot sun for extended periods of time as the heat will cause the air in your board to expand and potentially damage it by blowing a seam. This is obviously not an issue when you’re paddling as the water keeps the board nice and cool. Additionally, the sun’s ultraviolet radiation can deteriorate materials over time, so a little 303 Aerospace Protectant from time to time will provide added protection and prevent UV damage. 303 Aerospace Protectant won’t damage PVC, rubber, or plastics, and it’s safe to use on the Model X — just don’t apply it to the traction pad though as things can get a little slippery. Last but not least, if your board begins to look dirty, you can give it a quick wash with some mild soap and water.
