My 2010 came through with nice clean paint (black)and I couldn't detect any contamination on the surface. You can check this by putting your hand in a plastic sandwich bag and lightly drag it across the paint. If it catches and doesn't move smoothly over a clean surface you should consider claying it first and then go over with a good paint cleaner/polish like 3M Imperial Hand glaze. Now you should have a very clean swirl free finish to protect. I was recently introduced to Turtle Wax Ice products. I've used many different and higher priced waxes over the past 40+ years and I am very impressed with the results using the Ice products. The clear liquid I used has to be the easiest and fastest way to protect the cars finish. You can use it on paints, plastics, and rubber without residue cleanup and you can get some good build out of it. It did one coat per the instructions and washed the car again 3 days later and put another application on. Since then I've used the Ice detailer after each wash and the detailer with carnauba in it twice. I've had my car for a year now as my daily driver and the finish is still holding up. I also use the Ice car wash. I always apply and remove the products with a quality microfiber towel. If there are any streaks I mist with clear water and dry and buff with a soft 100% cotton towel. I have no affiliation, just very satisfied with the results.
