I've dealt with vehicle wraps for a bit, and if nothing else this will keep the paint looking fantastic. Rust may still get in around the edges and it doesn't like that one bit, but that's as likely as rust starting on a normal paint job.
Vinyl longevity is about a year in direct sunlight, maybe three if garage kept. After that it will start to crack and need to be replaced. The upside is that the paint underneath will still be factory fresh.
That being said the vehicle wraps I did were a printed vinyl with a clear lamination over them (one piece). I never dealt with JUST the clear, so I have no clue how long that lasts, how soon it yellows (if at all, etc).
So if this is "good" or not? I'm torn. Generally, paint lasts longer than vinyl, vinyl lets you get crazier graphics jobs, and both cost about the same to get done.
And if you do it yourself, compound curves with vinyl is a ******* to do. FYI.
