I have a 2012 Race Red GT, and I want to make it shine as much as I can. What more can I do? It's already been washed, polished, and waxed by hand. I want to know what I can do at home to get it looking as best as possible. Dual action polisher? Buffer? Any ideas or experience is much appreciated. I don't have experience wet sanding, and the idea of trying that myself makes me nervous.
