I guess depends on quality of person who put it down.
Everything fades in Sun but line x recent formula longer lasting.
I worked at GMC dealership several years and we sold trucks with line x. Never once saw crack or rust. If person does proper job spraying it then won't have gaps. My uncle truck was line x in 2001 when he bought and other than some fad no issues. And live in SC so plenty of heat and Sun.
Find a quality shop to spray, fix the issues you've had.
