Primer coats catamaran cabin top in golden hour light
What this video covers
Refinishing the cabin top of a Bali 4.4 catamaran requires a multi-step fairing and priming process to achieve a smooth finish.0:12 After removing the gel coat gloss with an orbital sander, the crew applies a blue guide coat to identify low spots, which are then filled with Total Fair epoxy fairing compound.0:37 Once cured, the surface is sanded with 120-grit sandpaper using a long board to ensure uniformity.3:46 The crew applies Alex Seal Finish Primer, thinned to 20–25%, in three coats to account for warm temperatures.4:25 To achieve a desired eggshell finish on interior bulkheads, the crew experiments with adding a flattening additive to Alex Seal Pegasus Gray paint, noting that the two-part epoxy paint provides significantly higher durability than standard hardware store alternatives.13:38 Separately, the crew prepares for a fall charter in Greece by studying for a captain's license through the online Mariner's Learning System, which offers self-paced modules for Six-Pack and Master certifications.5:20
