Supplier's note

  1. Three Technical Breakthroughs:

    • REACH certification: Ensures compliance with EU safety standards for chemical compounds.
    • ISO9001 quality control: Guarantees consistent performance across batches.
    • Rapid 5-minute activation: 20% faster than traditional leak stoppers, reducing downtime.

  2. Optimal Version Selection:

    • Base Model: Ideal for occasional drivers or small leaks (e.g., minor rust holes).
    • Advanced Model: Suitable for frequent drivers or vehicles in harsh climates (e.g., heavy-duty trucks).
    • Pro Model: Designed for commercial fleets or extreme conditions (e.g., high-temperature engines).

With the Pro version’s 140°C temperature resistance, you can safely handle engines in extreme environments. Pair it with its rust-proof formula to protect against corrosion over time. The Advanced Model’s enhanced corrosion resistance makes it perfect for coastal regions, where saltwater exposure is common. Choose the Base Model for quick fixes in everyday scenarios.
