My cars a year old, and has done nearly 9000 miles. I try to keep it clean, but its not always possible! However, I saw a picture of it when I picked it up, and it looked a lot brighter than it does now.. If I use AG Super Resin Polish, would that work? I also have AG HD Wax?? Ive properly polished and waxed it twice, over the year. What else do you recommend?
