How to fix scratches on a kayak?

To fix scratches on a kayak, first clean the affected area with soap and water, then dry it thoroughly. For minor scratches, use a heat gun or hairdryer to gently warm the area, which can help smooth out the material. For deeper scratches, apply a patch using a suitable repair kit designed for your kayak's material, such as fiberglass or plastic. Finally, sand the repaired area lightly and apply a marine sealant to protect it from future damage.
