Wear disposable PVC gloves, secure the repair area with tape so as not to stain other areas, squeeze out the boat gelcoat repair, use the mixing stick to mix the fiberglass repair well, apply it to the target area, let it sit for 24 hours, and then sand it with sandpaper to repair shattered fiberglass and deep cracks.
