KBS Coatings 5300 Gold Standard Tank Sealer – 1 Pint

Overview

KBS Coatings 5300 Gold Standard Tank Sealer is a premium, single-component, ready-to-use interior coating designed for metal, aluminum, and fiberglass tanks. Applied in a single step, it cures into a tough, fuel-impervious layer that lines the inside of the tank. The formulation targets common fuel-system challenges by sealing pinholes and weld seams, helping minimize moisture intrusion and fuel seepage paths. The cured film blends hardness with necessary flexibility to tolerate continuous vibration and the regular expansion and contraction caused by temperature changes. Built to withstand demanding conditions, this sealer offers a durable interior barrier without changing the appearance of the tank exterior.

The Gold Standard is widely recommended for its straightforward application and strong interior protection. By providing a unified coating in one coat, it aims to reduce the risk of rust and corrosion at critical seams while keeping fuel flow unobstructed. The finish is designed to endure the internal environment of fuel systems, where exposure to fuels, additives, and varying temperatures can be challenging.

Key benefits

• Impervious to fuels, alcohol additives, and most solvents
• Permanently seals pinholes and weld seams
• Flexible to expand and contract with temperature and vibration
• Withstands temperatures up to 600F
• Creates a durable, fuel-impervious interior finish

Real-world uses

• Refresh older tanks by protecting interior surfaces from leaks and corrosion

Technical highlights

The Gold Standard Tank Sealer is designed to form a robust interior barrier that resists fuel exposure while remaining flexible enough to cope with tank movement and thermal cycling. It is positioned as a long-lasting solution for interior tank protection, balancing rigidity with the necessary give to ride through engine and vehicle vibrations without cracking.
