Original paint except for the rocker panels and the side molding. The car has 130,000 original owner miles on it. It runs as good as it looks.
Have no experience with, or information on, Duragloss products. I really like Meguiar's MPPC for oxidation removal though. The neat thing about MPPC, is that besides removing oxidation well, it also cleans grime embedded in the pores of the paint. It brings the color back to the original color. If you have swirls or other blemishes I'd polish them out with Speed Glaze (#80) using the PC and a polishing pad at speed 5.
There are a lot of good products in the market. Find something you like and learn how to use it properly. MPPC and #7 can be used either by hand or by PC. If you haven't used a PC or rotary buffer before, I caution you to use care around the edges of any seams. Single stage paint is not as hard as clear coat and you can buff through the paint easily, especially on a 12 year old finish. Be sure to get some painters (blue) tape and tape around these areas and do them by hand after the rest of the car is buffed. Areas around the headlight covers and edges of the nose piece, for example, are likely to be thin. The wing and engine lid are others. Tape off the black vinyl and rubber areas to keep your polish and wax off of them. Some products will stain them.
You are probably beginning to see oxidation on your tail lights too. Get some Meguiar's PlastX for them and they will look like new.
