Ding All’s Sanding Resin Kits remain the industry standard for more complex home ding repairs on your river surfboard, and we’ve had good results with their non-yellowing resin and reliable catalyst-based curing. When mixed and applied well, the repairs come out durable and surprisingly professional-looking. However, this kit is very user-dependent. Perfecting the mix, cure, and sanding takes practice, and we’ve definitely had a few rough-looking repairs in the early days. If you’re confident in your skills—or willing to learn from a few YouTube videos—it’s a great option. But beginners should be prepared for the possibility of making a ding look worse before it looks better. Overall, it’s an excellent choice for those comfortable with hands-on repairs, but not the most forgiving kit for first-timers.
