My Cuda is base coat only, I didn't paint it, but it was painted back in '82. That's how it was when I bought it.
The car had some dirt and orange peel in it so I used 1500 wet & then 2000 wet.
After sanding I used Perfect-It III 3M #05933 with a white foam pad and then finished it with a gray foam pad & 3M foam polishng glaze #05996..
You have to keep the paper very very wet so you don't get any dirt in it or you will scratch the paint. Don't rush it, take your time... I had like 20 hours into it and I have a vinyl top..
If you have really nice paint on the car, leave it to a pro to handle....
When done right the paint will look like a mirror.......
