Best way to protect new Truck Box (underneath)

[gbfan10]

I am replacing my truck box with a rust free box from Texas. The road salt is awful around here and looking at my old box, you wouldn't believe the amount of rust that it had on it underneath. When i get this new box, would there be any benefit to sandblasting the bottom and applying epoxy primer and then a decent chassis paint? Or would the OEM paint be just as good? I don't want to replace this one again in a few years, they are getting very spendy.

we probably would. it reads like theres still a bed to the box- its not too rusted yet.

my opinion- use the epoxy but skip the chassis paint and use something like raptor liner.

four or five coats of epoxy and forget it, waste of money to use any coating over the epoxy unless its needs to be color of the truck.
