Direct adhesion on gelcoat, steel and light alloy, applied at both low and high thickness. Unikote PRO characterized by very high chemical-physical toughness, resists weathering, immersion, trampling abrasion. New formula with limited amine carbonation, which allows coating with enamels without staining; reduced whitening (blushing), so applicable as a professional finish even though its gloss fades more quickly than an enamel. Ideal coating for all workboats, due to durability of protection, applicability in less than ideal thermohygometric conditions, and practicality of using a single product for protection of opus viva, opus morte deck, and interior parts.
