What this video covers

Preparation of a keel for antifouling requires a systematic approach to corrosion protection and surface bonding. After sanding the keel to bare metal, applying a high-zinc epoxy primer like Interprotect provides sacrificial protection by supplying extra electrons to the metal, effectively acting as an anode.▶ 3:20 Filling divots with epoxy filler directly over the primer—rather than applying filler to bare metal—prevents moisture entrapment and separation between the filler and the metal surface.▶ 4:53 For sealing gaps at the base plate, applying paint to the metal before using 5200 sealant ensures a more reliable bond than applying the sealant directly to bare, shiny metal.▶ 5:38 While a full media blast and professional refairing remain the long-term goal, these interim steps provide sufficient protection for a 100-day window.▶ 7:56 Prioritizing essential structural and protective maintenance over aesthetic perfection allows for a faster return to the water and keeps the project within budget.▶ 11:10
