Today I used a clay bar on my car and WOW, what a difference! It was pretty easy and the paint is more smooth than most new cars. It was a Mothers kit that included the detail wax (used for lubrication during clay bar application) and some carnuba cleaner wax. That was the best $15 bucks I've spent in a while on detailing supplies. If your paint feels rough, you should consider using a clay bar, it's awesome!
