What this video covers

Repairing cosmetic gelcoat chips on a 1987 Catalina 34 requires a systematic approach to surface preparation, material application, and blending.0:35 Before addressing specific nicks, clean the surrounding area with acetone or a de-waxer and remove oxidation using a rotary buffer with a wool compounding pad and a high-quality cutting compound like Total Buff.5:21 For the chips themselves, sand only the damaged area and jagged edges with 120-grit paper to create shallow grooves for the new material.6:40 Apply non-waxed gelcoat in thin, multiple layers using a small applicator like a tongue depressor, allowing 30 to 40 minutes between coats.13:34 Seal the final layer with PVA to ensure a complete cure, then wet sand the area using 600, 800, 1200, and 1500-grit paper until flush.18:01 Finish by buffing the area to match the surrounding luster and applying a protective coat of wax.20:31 Proper preparation and thin, layered application minimize the visibility of the repair and prevent unsightly halos.
