68 Stang, I think that time I used Meguiars step 1 paint cleaner, step 2 polish, step 3 carnauba wax and step 7 glaze. Then when I'm done, I like to lightly mist the car with some quick detailer and wipe it down.
For getting scratches out, I really like Nu Finish's Scratch Doctor.
I've noticed that Meguiars works good for most colors, I've liked the results on my black car and the green F150 that I have. I had a true blue 01 GT, I would use Zymol on that, it really made the car look great, but it didn't seem to work as good on black.
I can post some pictures of my truck if you want to see how the same setup looks on a different color if you want?
What color of car do you have?
