Ce que couvre cette vidéo

Restoring oxidized gelcoat requires a graduated approach, starting with the least aggressive cleaning methods to preserve the thin protective layer. Begin by scrubbing the hull with boat wash and sponges, using Scotch-Brite pads for stubborn oxidation.▶ 2:45 If washing fails, use a buffer with a mild buffing compound, which acts as a gentle sanding process.▶ 3:24 Reserve conventional wet sanding with 2000 to 4000 grit paper as a last resort, as it risks sanding through the gelcoat entirely.▶ 3:59 Once the surface is clean, apply a marine-specific wax with UV protection, such as Colonite Fleet Wax 885, Meguiar's Flagship Premium Wax, or 3M Marine Ultra Performance Paste.▶ 4:53 Work in small 2-foot by 2-foot sections, allowing the wax to haze before buffing with clean microfiber towels.▶ 5:38 For severe damage, apply new gelcoat mixed with 1–2% MEKP catalyst, sand progressively from 600 to 2000 grit, then buff and wax.▶ 7:16 Proper maintenance prevents the gelcoat from becoming porous and susceptible to further degradation.
