Hell yeh man that dont look bad at all!
But let me shine some light on this bed liner thing, white colored spray on bed liner is poo! The white will turn yellow before you know it, now what i did in a show truck i built a few years ago is Spray the bedliner and let it dry once dry and untouched spray a base coat/ clear coat on it and you want have to worry about any fading or dulling out it will stay nice and shiny white! It holds up a little better than you would think ill try to find a pic of my truck bed somewere.
Here ya go the fuel cell and side rails are done like I explained above, hope this helps!
