What does 'proper maintenance and care' mean?
Mostly, washing the car regularly and gently. Hand washing is best, a touchless wash is next, and you never aim a pressure washer at the film's edges. The full routine is in How do you wash and care for PPF?
If you'd like a record that the film was cared for, an annual maintenance visit at APC counts as documented proper care. You don't have to do it to keep the warranty; it's simply an easy way to show the care happened.
Does Seattle weather shorten PPF's life?
Rain itself doesn't hurt film. What wears on any car here is grime that sits: road film, pollen, sap and bird droppings. Wash regularly and remove sap, bugs and droppings promptly, and the film keeps doing its job.
