Buying Guide

Choose the right formulation

Pick oil-based topside paints for traditional durability or 1-part polyurethane for easier application and high gloss on fiberglass

Match product to substrate

Use gelcoat-specific compounds for polyester or composite hull repairs and topside paints formulated for fiberglass for best adhesion

Consider finish and UV protection

High-gloss or polish options with UV inhibitors preserve appearance on sun-exposed topsides and reduce chalking

Check coverage and package size

Compare quart coverage and whether multi-packs are offered to avoid shortfalls on larger projects

Prep and compatibility matter

Ensure proper sanding, cleaning, and compatibility with existing coatings to prevent peeling or lifting
