What this video covers

Fairing and sanding the hull of a 50-foot custom sailboat requires a systematic approach to achieve a smooth surface before applying a base coat. To identify low spots, the builder applies a graphite powder guide coat, which reveals irregularities after sanding with a longboard.3:06 A large disc sander removes approximately 70% of the material by targeting high spots, while the longboard provides the final precision for the remaining 30%.4:05 The builder avoids wall sanders, noting that their soft discs and lack of control make them unsuitable for achieving a truly fair surface.5:05 After filling low spots with epoxy fairing compound, the builder allows the material to cure and settle to minimize future shrinkage.15:38 The process is labor-intensive, requiring several weeks of manual sanding to prepare the topsides for a high-gloss finish.15:48 The builder prioritizes the topsides over the area below the waterline, where minor irregularities are acceptable.7:12
