Buying Guide
What to consider when choosing an anti belt slip spray:
- Application type: Aerosol sprays spread evenly and dry quickly; gels or liquids may need longer drying times.
- Belts covered: Verify compatibility with serpentine, timing, or drive belts and the vehicle type (car, truck, SUV).
- Traction vs. noise: Some products prioritize anti-slip, others focus on silencing squeaks; choose based on primary concern.
- Wear protection: Look for formulas that protect against drying, cracking, and aging of rubber belts.
- Reapplication frequency: Harder driving conditions or extreme temps may require more frequent use.
- Ventilation and safety: Use in a well-ventilated area; avoid contact with painted surfaces and hot engine components.
How to apply
Clean the belt area to remove dirt and oil. Apply a light, even coat along the belt’s length, avoiding pulleys and open belts. Allow to dry fully before starting the engine. Reapply as needed if belt noises return or slippage reappears.
