With proper care and maintenance, clear bras should last the term length of the corresponding manufacturer’s warranty. We have seen a number of our customer’s cars a few years beyond the length of the warranty with the film still being in great shape. Again, it depends on how you maintenance it.
The current industry standard warranty period for clear bra is 5 years, and a few films offer 10 years of warranty coverage, depending on the product installed. Be sure to ask what the warranty period is and what the warranty covers before having any clear bra added to your vehicle.
