Novol 34012 Cavity Wax Spray (500ml) – Internal Corrosion Protection
Protect the hidden internal structures of your vehicle with the Novol 34012 Cavity Wax Spray. This 500ml aerosol is a specialized, wax-based preservative designed to penetrate and seal closed sections where moisture and salt typically accumulate.
Unlike external underseals, this wax is formulated for high "creep" capability, allowing it to flow into tight seams and joints to stop rust before it starts.
Key Features & Benefits
- Deep Penetration: Excellent capillary action allows the wax to "creep" into spot-welded seams and overlapping metal panels.
- Moisture Displacement: Actively pushes moisture away from the metal surface, creating a hydrophobic barrier.
- Flexible Protective Film: Dries to a semi-transparent, amber-toned waxy coating that remains flexible and will not crack or peel over time.
- Salt & Chemical Resistance: Provides long-term defense against road salt and winter road brine.
- Convenient Application: Includes a long, flexible extension wand with a 360° nozzle for reaching deep into sills, pillars, and frame rails.
Common Application Areas
- Sills (Rocker Panels): The primary area for internal rust on most vehicles.
- Door Interiors: Protects the bottom "hem" seams where water collects.
- Chassis Rails & Box Sections: Vital for structural integrity on older or off-road vehicles.
- Bonnet & Boot Lid Reinforcements: Seals the hollow support structures.
Professional Application Strategy
For the most effective protection, the wax must be applied inside the "box" sections of the vehicle.
Application Steps:
- Preparation: Ensure the cavities are as dry as possible. Clear any drain holes of mud or debris.
- Agitation: Shake the can vigorously for 2 minutes.
- Wand Attachment: Securely attach the flexible extension wand to the aerosol nozzle.
- Insertion: Insert the wand fully into the cavity through an existing drain hole or access bung.
- Extraction: Spray the wax while slowly withdrawing the wand. This ensures the internal walls are coated evenly.
- Cleanup: Use Novol Plus 780 to wipe away any wax that drips onto exterior paintwork.
Expert Insight: It is best to apply cavity wax on a warm day. The heat helps the wax remain fluid for longer, allowing it to penetrate deeper into the tightest metal seams before it sets.
