This small chip is from a stone that was thrown from a car.
Begin by scraping away any loose gelcoat around the damaged area with a razor blade.
Then sand the area lightly with 400 grit sand paper.
Next, use acetone on a clean rag to eliminate any remaining dirt and dust. Use the acetone sparingly as it can also dissolve good gelcoat if left on too long. Also, do no blow dry the area with your breath since this will introduce moisture into the damaged area.
Prepare the gelcoat resin according to the manufacturers specifications. Use a toothpick or a small clean screwdriver to stir the gelcoat thoroughly.
