Good-quality paint protection film lasts for years, not months. Polyshield film is backed by a 10-year warranty when an installer fits it, and 7 years when you fit a DIY kit yourself. How long it lasts on your car comes down to the install, the paint underneath and how it is cared for.
What affects how long PPF lasts
- The installation. Clean prep and well-sealed edges stop film from lifting. Most early failures start at an edge.
- The paint underneath. Film holds best on factory paint that has no ceramic coating or sealant such as wax. A poor respray can let go of the car, and take the film with it.
- Sun and heat. Constant UV and high temperatures age any film faster. A car garaged at night will keep its film looking newer for longer.
- Care. Gentle hand washing keeps the topcoat working. Harsh chemicals, brush car washes and a pressure washer aimed at the edges shorten its life. See How to wash a car with PPF.
How the warranty relates to film life
The warranty is the minimum Polyshield stands behind, not the point where film stops working. Installer-fitted film carries 10 years, because a trained installer controls the prep and the edges. A DIY kit carries 7 years. Both need the film registered and looked after as the warranty terms describe. See PPF warranty explained.
Signs your film needs a look
Edges that lift, cloudiness that doesn’t clear after a few weeks, or a cut through the film are worth showing to an installer. Light swirls and marks in the topcoat usually heal with warmth or wash out.
