Your clear bra’s longevity relies on several factors, most importantly, the quality of the film, how much sunlight it’s exposed to, and how well you take care of the product.
For example, a car kept in a garage has a longer life-span than one exposed to the sun. The manufacturer’s warranty on paint protection film varies from three to ten years. Your film should be inspected at the four- or five-year mark to determine if it needs to be replaced.
