Our cost guide explained why topside resprays price the way they do; this article walks the job itself, because owners who know the stages can hold quality at the points where it is actually won and lost.
Stage one: diagnosis and strip decision
Adhesion tests and moisture readings decide whether existing coatings stay as substrate or come off, the gelcoat versus paint logic from our GRP article, with any osmosis findings dealt with first per the blister guide. Getting this wrong is the root of resprays that fail in year two.
Stage two: fairing and high build
Epoxy fillers fair the hull, longboarded until guide coats sand off evenly, then high build epoxy primer seals the work. This is the stage that consumes the skilled days the quote paid for, and the stage cut first by cheap jobs; gloss is merciless about what lies beneath, per our gloss retention article.
Stage three: the finish system
Two coats of two pack polyurethane, sprayed inside containment against Gulf dust, with dew point discipline from our humidity guide governing the schedule. Roll and tip remains the honourable alternative for workboats and budgets, a step below sprayed gloss, far above tired gelcoat.
The hold points an owner should attend
After fairing under guide coat, before primer: sight down the hull in low sun. After primer sanding: verify no breakthroughs or pinholes. Before finish coats: agree the final colour against a sprayed sample panel, not a chart. And at handover: film records and product batch details into the boat's file, the habit every article in this series keeps recommending.
