As JasonC8301 said, Zaino makes a polish specifically for single stage (non-clear coat) paint. Its called Z3.
Zaino is easy to use. I highly recommend it. Your procedure would be:
Get the paint in shape as needed. You will need clean paint to start with. This may mean using a mild abrasive to remove oxidation (which happens with single stage paint).
1. Dawn wash
2. Clay, using Z7 car shampoo as the lube.
3. Wash with Z7, rinse and dry.
4. Apply Z1. Do not remove. No need to let dry.
5. Apply Z3.
6. Let the Z1/Z3 dry.
7. Polish off the excess Z1/Z3 with 100% cotton towels.
8. Wipe the car down with Z6, wipe dry, for a brilliant gloss.
Thereafter, after you wash your car, throw on a coat of Z3, let dry (dries quickly in most climates), and remove. Wipe on the Z6. When the car gets as glossy as you want, you can stop adding coats of Z3. I have ten coats of Z, but you only need one for protection purposes and the car will look great with just one.
But, after the initial session, putting on additional coats is, by comparison, easy, so some people put on great numbers of coats.
The great thing about Z is that you can just keep layering coats, as long as you allow enough curing time between coats. Sal Zaino says 24 hours. DK and I, and Ron, I believe, and others, think that auto protectant polymers continue to cure for longer than 24 hrs. I give a full week between coats . . . this allows the prior coat to get really hard, so I am building up layers.
