“HS” antigravilla in two-component polyurethane, ideal for restoring body protections and sealing. It can be applied directly to metal, prepared bottoms, paints or reinforced resins. Repaintable once dry with any system. It includes the catalyst. The boat is designed to fully open the metal top cover, thus facilitating the correct mixing of both products. Applicable with standard antigravel gun or disposable caps (always clean).
