what about rock chips? the guy i bought my car from put a lot of highway miles on the ES, and the hood shows it with all of the rock chips. they're not rusted or anything, but they're definitely past the paint. they're deep and you can feel them when you rub your finger over them.....plus they make the front of my hood an eye sore. original lexus touch up paint will probably be my best bet??

also, i've got about a 6" x 1" streak on the back of my car, right next to the antenna. it looks a lot like a sun spot.....the paint sort of just disentigrated there, and it's blackish/grey where the paint used to be. it's not getting any worse, but i'm wondering if there's anything i can do about it.
