The Paint Manual - Hempel

Repainting all substrates
Maintaining coatings helps the protection, appearance and
value of your boat. Both two component and single component
finishes need repainting. How often varies from boat to boat,
depending on the existing paint system, usage, general wear
and tear, mooring conditions and UV degradation.
