It depends on how the box is designed, if there are places the fertilizer can be trapped and not washed out of but otherwise just make sure the tarp is in good condition and if the walls are bolted to the box base I'd suggest parking the truck under a roof or regardless actually if its going to rain any amount to reduce the chances of water finding its way in. Then after seeding empty it all out, and if you can't get to it right away to wash, again tarp rolled over and into a shed but try to wash out the box as soon as you can and blast away a few times at all seams/joints inside and outside and wash all tarp hoops and the tarp caps underneath and tops etc, open the rear slide and wash out the track grooves. Go over all surfaces a few times inside the box and as fert dust swirls around when loading the truck it gets everywhere so wash the outside of the box and the truck cab and get the top of the cab as well. I've seen it so many times when seed drills, grain boxes, trailers or anything that handles fertilizer are not washed and the moisture from the air does its magic, that is what kills the metal. Wash it well and chances are the box will outlast you if its in good condition now, yes painting it would be a good thing to do but in all honesty I've done this for so many years and the paint is worn off of parts of the floor and its never been an issue.
As SWMan said, certainly no harm in applying diesel to non rubber surfaces before/after the fert was handled but just don't do what I've seen so many times with old timers ( yes will probably hurt someones feelings here with this comment ) thinking it was so horrid to ever bring water near to their fert covered equipment to wash it so they applied diesel to the fert scum and it may have slowed down the rusting but most often the seed drill etc they did that to was rusty within a few years of being new. If your contemplating painting the box in the next while I would not apply diesel for the reason of it getting into the steel and causing possible paint adhesion issues.
