What this video covers

Refinishing a boat hull with two-part LPU paint requires extensive surface preparation to achieve a professional-grade finish. The process begins with structural fabrication, including tabbing in new combing boxes and gluing custom carbon-fiber landing pads to the deck to distribute hardware loads and prevent leaks.0:46 After filling pinholes with fairing compound and sanding, the entire vessel is coated in primer.6:34 Achieving a smooth surface necessitates multiple rounds of sanding, progressing from 120-grit to 220-grit, and finally to 320-grit for the entire hull.13:33 High-traffic areas may require a second coat of primer, followed by additional sanding to eliminate orange peel and surface imperfections.11:09 Nooks, crannies, and curved sections inaccessible to power sanders require meticulous hand sanding.14:00 Before applying the final topcoat, the surface must be thoroughly washed, dried, and chemically wiped to ensure proper adhesion.17:08 A high-quality paint job depends on this labor-intensive prep work, as the primer must feel as smooth as glass to the touch.16:37
