Notes: Under extreme conditions, heat the neat fluid (60°C max) for sprayability. No significant increase is achieved with a stronger mix of type 1. Kilfrost is normally mixed 50/50 or 60/40. The Freezing Rain columns have been replaced in some countries with Light Freezing Rain and Freezing Drizzle.
