I was thinking of having one of those spray-in bed liner materials applied to the lower body panel areas (where the lower paint is on the two tone paint) because of all the rock chips and dings from other car doors. I'm concerned if this will look awful or if the color will fade over time and look tachy. I have seen some spray-in liners that have a fairly fine texture and look pretty sharp in the bed. Or would I be better off to go to a body shop and have the bottom of the panels repainted with some kind of rock chip prevention coating. Any input would be appreciated
