How to get my clear coat back?

I recently installed a new hood on my truck, and when I went to purchase it im not sure what he did but it looked really sharp and matched my paint great, but now after having it a couple months its all faded out and white looking and doesn't match anymore. I try keeping it under a tree as much as possible but when it sits at work all day its near impossible. I know its that because my truck gets well taken care of, I have no doubt there is more wax then paint on what I bought originally, but having to switch hoods and now his does not match. I rubbed it down good once with rubbing compound and came right back over with a thick coat of wax right away, but it still didnt last. The hood has a really nice shine like the rest of the truck, but the color does not match, and mostly from the clear coat "fogging".

It is a Dodge doing what Dodge clear does if you don't take care of it, but I have 4 trucks in my family alone that prove a little love and Dodge paint, body, and clear will last forever.

Is my only option to have a body shop repaint the whole truck?
