Hardwood over a steel bed?

[weircc]

So i have been doing some thinking about my truck im in the process of putting it back together when i get this bright idea i want a wooden floor but i have steel at the moment. Now the truck is already painted except inside the bed cause i was going to to a line-x to match paint.So is it too late or can i install wood over the steel? whats the skinny on doing wooden floor.
