Power Tank Gum + Plastic Primer is a complete kit to repair and protect the inside of tanks up to 50/55 litres, even with porosity and micro-leaks. The combination of an elasticised sealing resin and a nanotechnology epoxy plastic primer delivers excellent adhesion on plastics, resins and technical materials, as well as steel and aluminium. Fuel tank treatment that’s easy to apply for advanced DIY users, resistant to petrol, diesel, oil and premix for long-lasting internal protection.

Power Tank Gum + Plastic Primer Kit is a complete system for internal tank restoration, designed to solve common issues such as rust, porosity, wall thinning and micro-holes. The treatment creates a strong, durable internal coating, ideal for motorcycles, cars, tractors and agricultural or industrial vehicles.
The kit works in three key steps:
Phosphating rust remover (750 ml): removes rust and prepares the surface, improving adhesion.
Power Tank Big Gum (1.3 kg) + hardener (100 g): high-elasticity epoxy sealing resin with strong filling capacity, creating a continuous internal barrier.
Nanotech Plastic Primer (720 g): flexible epoxy primer designed to maximise bonding on plastics and composite materials.
Power Tank Plastic Primer uses nanotechnology to achieve high bonding strength on difficult substrates. This makes the kit suitable for advanced DIY applications, delivering a professional finish and long-term durability.
Once applied, the treatment forms a permanent anti-corrosion internal coating, fully resistant to:
petrol
diesel
oil
premix
It also helps prevent rust particles from breaking loose, protecting key fuel system components such as carburettors, fuel pump, fuel filter and injectors.

Specific References
We used the kit on an aluminium tank with slight seepage and a thinning area. Big Gum has excellent filling power and stays elastic after curing, with no cracking. The plastic primer is a real advantage when working on composite tanks too. Solid technical product, recommended for long-term internal repairs.

Restauré un depósito de plástico (ABS) con porosidad y una pequeña fuga. El primer nanotecnológico mejora mucho la adherencia y hace el trabajo más seguro que selladores genéricos. Una vez seco, el interior queda liso y bien recubierto. Kit completo y equilibrado para regenerar y proteger el depósito.
