Gelcoat filler

Thoroughly mix the filler with about 2% hardener. Sand and clean the damaged area before applying the filler. The space you are working in must be at least 17°C. Apply a thin layer. For the final finish, use wet sandpaper in grits 600-800-1200. Then use a rubbing agent, polish and wax.

Keep in mind that colours may vary between different products or applications, and that the old surface may be faded or oxidized.
