So I have this 06 ranger that is in decent condition it has some rust underneath but nothing super concerning and it runs smooth. But the previous owner had some rust in around the wheel wells (?).and they used some bondo and matching paint to try to cover it. Well, it looks quite bad. Any thoughts on what I can do to make it look better? Is it worth doing? Regardless this is gonna be my truck till it dies but if it was doable and cheap I'd like to get rid of the eye sore factor.

One suggestion I got was to look for a new bed used from a part out

 

Swap out the bed. See if you can find one at your local pick and pull.
