For installing illmatic PPF, use clean, filtered or distilled water mixed with a small amount of shampoo that contains no conditioners, moisturizers, or additives. The shampoo acts as a surfactant, allowing the film to glide smoothly across the surface before final positioning.
A standard starting mix is:
• 1 gallon of distilled water
• 2 to 3 ml of baby shampoo
This creates enough slip for panel alignment without over-lubricating the adhesive.
