I just finished using Meguiar's clay bar kit on my 08 Jetstream blue coupe. The stuff is amazing! There was nothing wrong with the paint, it was just a little rough for my liking. It took about 1 hr, then went over the car w/ polish, then wax & the color looks sooooo much deeper. Even my wife commented on how deep the color was. The surface is slick & smooth too. It's definitely worth the time & money.
