Definition
A warranty states contractual coverage and conditions. Service life describes how long the installed film remains suitable in its actual environment.
Why it matters
Read named defects, exclusions, care duties and who handles a claim. A warranty term is not a universal replacement interval or a promise that road damage will be covered. Keep product and installation evidence together.
Apply the concept
PPF lifespan, inspection and removal
Distinguish service life from warranty and plan what to do when film ages, lifts or is damaged.
