This is a good field repair kit for minor incidents that can happen in the field to the kayak fiberglass hull that need immediate attention. However, I would add the following items:
1. A small brush for spreading the resins on the area to be repaired.
2. A pair of serrated scissors for cutting the fiberglass cloth.
3. A roll of fiberglass cloth with woven sides so that they don't fray when cutting.
You can see in the YouTube video below from Half life the Ding All repair kit being used to fix a surf board. The Process would be similar for a kayak.
