This 3 Litre bulk pack offers an economical and professional-grade solution for body shops requiring a reliable, high-build primer-filler that balances excellent filling properties with an effortless sanding experience.

Key Features & Benefits
- High Build & Filling Power: Specifically formulated to level out deep sanding marks (P240–P320), surface irregularities, and minor imperfections in fewer passes.
- Optimized 3:1 Mixing Ratio: A user-friendly ratio that provides a balanced pot life and a fast, thorough cure when used with the appropriate Novol hardener.
- Superior Adhesion: Bonds exceptionally well to various substrates, including polyester fillers, existing paintwork, and properly prepared steel or aluminum.
- Exceptional Sanding Properties: Once cured, the filler sands smoothly without "gumming" or clogging sandpaper, allowing for a faster transition to the basecoat stage.
- High Solid (HS) Technology: Delivers a high film thickness per coat, reducing material waste and application time.
- Anti-Corrosive Properties: Provides an essential layer of protection for the substrate, preventing rust and ensuring a long-lasting repair.
Professional Application Tips
- Mixing: For the best results, use the Novol N39699 (2:1 / 3:1) Measuring Stick. Precise measurement of the 3:1 ratio is vital to ensure the filler achieves its full hardness.
- Flash-off: Allow 5–10 minutes between coats at 20°C. This prevents "solvent trap," which can lead to pinholes or shrinkage later on.
- Sanding: Start with P320–P400 for initial leveling and finish with P500–P600 (dry) or P800–P1000 (wet) before applying your topcoat.
- Basecoat Compatibility: Protect 333 is compatible with all modern solvent-based and waterborne paint systems.
Why Choose the 3-Litre Protect 333?
The N37512 is the ideal choice for "full-car" primes or busy workshops. It offers the same premium leveling quality as the Protect 330 but in a larger format and a specific 3:1 chemistry that many technicians prefer for its slightly different flow characteristics and drying window.
