Well to create your deepest shine that will all start with a clean smooth surface.

So a clay will be in order as you have already stated you want to do.
Next you will want to identification the condition of your paint. Does it have swirls, scratches, holograms, oxidation, or clear coat failure just to name a few.

Once you have done that. The comes the most important step is doing a "Test Spot". The main things to keep in mind is to dial in the process on the test spot so that you know exactly what to do on the entire car. You will always want to start with the less aggressive method test it out and check your results. Some times car with a soft paint that is easy to work with can just need a polish and a wax. Others that have very hard paint and are tougher to work on would need something like a compound followed by a polish that's what makes the test spot such an important step.
Once you have your test spot figured out and u achieve the results that are satisfying to you then you can proceed to the rest of the car.
What all product and tools do you have available to you?
Work by hand is an arm killer and I know it will take a lot out of you. There are cheaper ways to get you onto a machine like the Harbor Freight DA. This is a good idea for those that don't want to spend $150 on a polisher. That something you may want to look into. I know there is a thread on the performance of the machine and it has HF DA in the title
If I'm not mistaken.
All your gloss and depth will come at the polishing point of your work tho it can be done greater results in less time and without killing yourself can be done with a machine.
