You will have to clean the kayak surface with detergent and a dishwasher to remove dirt or mildew. Now you have to apply the automotive colour polish, which matches the colour of your plastic kayak. When you’re done applying this colour polish, you can use the gel protectant that will protect your kayak from the UV rays. This process is done; all have to do is just wait for 3 days before you begin using it perfectly.
