So, I've finally had some time to give the Centennial a good detail, aside from the weekly cleanings. I used a PC with Wolfgang products, and I think it came out pretty good. I used the total swirl remover, followed by a finishing glaze, and topped it off with a sealant. For the interior, I used Aerospace 303 and Meguiar's Gold Class leather cleaner/conditioner (not the spray). In any case, I am always open to suggestions on cleaning products, especially for dark-colored cars! Being that the car is black, it's been difficult keeping it looking clean, but I think that black is a really nice color on a car when it is all shined up. With just over 52K miles, this Taurus runs as good as it looks (knock on wood)!
