don't think clay bar will fix oxidation but it will take a lot of junk that gets imbeded in you paint out. you would be surprised at the crap that is in your paint. i clay barred my dodge dakota 2-3 times a year and kept about five coats of wax a season on it. very clean truck at the time. you will need a cutter wax or a polish not really one that is a protectant but to polish it first. Mequires gold class worked good on my black 5.0 had a few spots on the front fenders did a pretty good job and i followed that up with the nxt. also rain dance or turtle wax makes a good protectant wax for ultraviolent rays and stuff. i deer hunted and used my dodge as a street truck and it kept a very wet looking paint job with very minimal damage to paint and it was black.
