i got some body parts that are more faded then the rest of the paint..

so i just wanna repaint it quickly, how should i do it?

I dont have a paint gun or anything like that so what kind of Can paint should i used?

Should i sand it with some 320 grit then prime it and paint it?

 

Go to the paint store and pick up some cans of paint that they mix for your color car. Should work out good for ya.
