Don't listen to the guys that obsessively wax and clay bar their cars. If it bugs you, fix it, but if it is all good, don't bother. These cars are meant to be driven.
If there are scratches that go through to steel, aka roof doors, rear, then it might be worth fixing it, but otherwise it is overkill unless you enjoy doing that sort of thing.
I love teasing the crazy clean people. I bought my Yaris in May of 2006. I cleaned it myself one time, because I was in florida at the time and the love bugs were attacking it. It was also cleaned once when I had it in the auto body shop because I can't see in dark and stormy weather and I sideswiped a stop sign in a massive parking lot. That's it. I've never waxed it, I've never otherwise paid to have it detailed. It lived 6 years On the Cape near the ocean, gone through snow and salt, and 3 years in central florida crap weather. No rust anywhere. And there are people who have had the paint peel to the primer for some strange reason and other screwball things, I bet it is because they wax and claybarred it weekly.
