A professional spray on liner is usually several times thicker than a paint you put on yourself, so it's more durable. But with that said, especially for an older truck, the Plasti-Kote liner may be plenty good enough.
For looks, these Plasti-Kote liners are a huge improvement over an old rough bed. The look is just about as good as a professional spray on liner.
Our liner after a year of use still looks almost as good as new. The coating is scraped away in a few places just from hard use. Plasti-Kote makes a small spray on can so these dings can be easily touched up. Another thing that happens is the little rubber texture materials gets broken out of the paint coating if you really slide heavy, rough stuff on the bed. What you see is little white dots where the rubber has broken out. This doesn't really hurt anything and isn't noticeable.
