Expert Analysis

Uses a concentrated 20-25% dimethyl siloxane base in an alkaline water-based system at pH 11.5. The high silicone concentration creates a durable protective film that provides UV and ozone resistance while delivering high-gloss results. The alkaline formulation helps the silicone adhere effectively to rubber and plastic surfaces.

Key Differentiators

  • High 20-25% silicone concentration provides enhanced durability compared to typical tire dressings
  • Multi-surface compatibility extends use beyond tires to plastic trim and wheel wells

Potential Concerns

  • High pH (11.5) may cause skin irritation and requires proper handling
  • Silicone-based formula may attract dirt over time and create dependency for reapplication
