What this video covers
The crew of a Lagoon 450 performs extensive structural repairs on both rudders and the aluminum fuel tank while the vessel is on the hard. After discovering moisture inside the rudders, the crew cuts open the fiberglass skins, removes the waterlogged foam core, dries the interior, and refills the voids with liquid polyurethane expansion foam before re-glassing with epoxy.0:58 During a separate inspection of the fuel tank to address diesel bug contamination, the crew discovers severe pitting on the aluminum floor, with some spots nearly perforated.11:43 Because the tank is inaccessible for removal, the crew plans to apply an epoxy-based barrier to the interior floor.11:18 They seal the inspection hatch using fuel-grade thread sealant, fiber washers, and a nitrile rubber gasket.14:20 Additionally, the crew performs hull fairing using long boards to ensure surface flatness, followed by a professional gelcoat color match using a spectrometer to blend repairs on the topsides and transoms.18:58
