Why would a 2002 Ford F150 run loud?

My dad owns the truck but I drive it frequently. A few months ago we noticed a knocking sound and there were issues with accelerating once you hit 50 mph. After having it looked at the mechanic temporarily fixed the issue. We still don't go more than 55 mph and never use the freeway.
Anyway. To me (at times) it seems as if the truck runs louder than it should. On start up it's a really loud roar and whilst driving it sounds as loud as an 18-wheeler. I don't drive it until it's warmed up so I don't think it's a cold engine then again, as you may tell, I don't have much knowledge on trucks/cars. Any help or theories is greatly appreciated.

How to get rid of surface rust on my truck hood?

I have a 1990 Ford F-150 and it is in terrific shape. Not any rust on it except for a layer of on the hood. I don't mind it, but I must admit the brown is jarring when the truck is sky blue. So how do I go about removing it? I heard sandpaper will do the trick. So if I plug in my hand sander and go to town on it, will I see results? Also, I plan to repaint the hood. What primer should I get? And what paint brand do you prefer? Any and all help is appreciated!
