Cosa tratta questo video
Fairing the cabin top seams on a catamaran requires a systematic approach to sanding and priming to ensure a smooth, protected finish. After glassing the cabin top seams, the crew uses a six-inch sander with 120-grit paper to fair the Total Boat Epoxy Ferrying Compound.1:03 A vacuum system collects dust, though operators must wear face masks and ear protection during the process.2:55 To identify low spots for future filling, the team plans to apply a blue guide coat after the initial primer application.1:43 For the first coat, they use Alex Seal finish primer, mixing a one-to-one ratio of base and converter with a 15-minute induction time.7:35 Despite increasing winds that threaten to blow away paint trays and cause debris, the team applies three coats of primer to the cabin top.8:30 The project continues with fairing hull seams, where the crew uses a small belt sander to prepare the surface for a final strip of glass and fairing compound.11:53
