What this video covers
The crew of the Lagoon 450 catamaran Parlay Revival repairs extensive hurricane damage to the hull by applying a mixture of polyester resin, gelcoat, and Cab-O-Sil filler to low spots.2:56 To restore the hull's original shape, the team uses longboards with 60-grit sandpaper to wet-sand the filler, marking remaining depressions with a pencil for subsequent applications.9:42 Simultaneously, the crew strips multiple layers of old antifouling paint and blue epoxy from the hull using 80-grit grinding discs and an orbital sander, aiming to reach the original gelcoat.12:09 They plan to use specialized antifouling paint for the aluminum saildrives to prevent galvanic corrosion.13:08 During the project, a severe lightning storm prompts the crew to disconnect the boat's batteries as a precaution.14:11 A significant setback occurs when an overly thick application of filler requires an entire day of additional sanding to level.15:14 The crew concludes that applying filler sparingly is essential to minimize labor-intensive sanding.15:21
