After a few years with minimal maintenance.
This is first-gen Ventureshield film. I'm pretty sure the owner did very minimal maintenance to it-- occasional wash and wax, maybe some occasional plexus (which is a big no-no).
So, if you have a clear bra w/ older generation material on a light colored car, you better be cleaning it regularly (with ppf specific cleaners) and sealing it or else you'll have this yellowish mess!
