Has anyone used spray on bed liner to cover the whole truck? If so what are the pros and cons?

 

Pro's:
- Easy clean with a power washer
- Will never need to wax the paint again after washing.
- Will not have to worry about scratches as much
- Repairing the liner is as easy as a spray can away

Con's
- Adding additional weight to the truck - probably minimal
- Insignificant drag added to vehicle due to rough surface

Just a few off the top of my head.

When I worked for Disney (Resort Transportation) we worked with Anaheim PD Traffic control and they coated their rangers beds and sides with spray on bed liner and they looked awesome. They had the shiny black version which looked great at night with the emergency lights and orange traffic light bars.

 

One con I can see is if you don't like it you're pretty much stuck with it unless you feel like sandblasting the entire truck.

 

By the time you see the body rust, it's way to late to try and save it.

 

Flex seal can fix body rust too.
