Something that small can be taken care of with Suncure really . I like using a small paintbrush for areas like that , just to make sure it gets into any small crevices . After you apply a small dab on there , get some 80 to 100 grit sand paper and sand it down , then put another layer of suncure on it . There will be less area to get resin in , but it ' s just to make sure you have a good seal . Hit it with 80 100 grit again , then use a 180 grit to finish it off . For any more serious dings , I always use the Ding All resin . It ' s just way better than Sun Cure . Sun cure is great for small dings like you have though . Repairing your surfboard is actually pretty easy , you just gotta try . The great thing about Poly boards is if you mess up the repair , you can just sand it out and start over . Also may not be a bad idea to get a nose guard . If that ' s still a thing .
