What this video covers

Camille and Jesse sand, prime, and antifoul the hull of their sailboat Stella in a boatyard before a planned passage to remote Indonesia, where no boatyards or spare parts are available.▶ 0:24 Starting with three to four days of sanding using 60- to 80-grit paper, they strip the hull back to primer and in some areas to gel coat, working in roughly 35°C heat and starting as early as 6 a.m. to beat the worst of it.▶ 8:34 Hull divots from impact damage are filled with a microballoon-and-epoxy paste, sanded smooth, then the entire hull is wiped down with acetone before painting begins.▶ 5:10 They apply two coats of PrimerCon primer from International Yacht Paint, thinning it 5–10% with thinner to compensate for the heat, then roll on five coats of Micron 99 antifoul, waiting roughly six hours between coats.▶ 9:01 The Micron 99 is a professional-grade ablative system; the extra coat count is deliberate preparation for warm tropical waters where marine growth builds fast.▶ 11:34 Neither Camille nor Jesse had prior boatwork experience before this haul-out. The job confirms that surface prep — sanding back fully and cleaning with acetone — is the critical variable in antifoul adhesion, not the number of paint coats alone.
