Woah, thats an awesome explanation for a noob like me! Thanks! I'm just curious though, could polishing ever remove paint or the clear coat in it's entirety. I mean, if it's similar to sanding a piece of wood...when you sand wood, you're removing layers of wood. Therefore, if you have a car for say 5 years and continually detail it and polish it quarterly, wouldn't you eventually be doing more harm then good?
When using a dual action polisher like the Ultimate Detailing Machine (UDM) or the Porter Cable 7424 (PC) you would REALLY have to try hard to remove enough clear coat to cause problems. Those two machines do not have the ability to really do much damage what is the good news about them. The bad news about those is they simply cannot correct paint near as fast and effective as a rotary which CAN remove enough clear coat to damage your paint. If you plan to buy a machine as a noob, I would recommend the UDM, it is more powerful than the PC (and thereby can correct better) but it is not powerful enough to do much damage.
Also, if you are planning to polish quarterly, you REALLY enjoy polishing. There are some on here who polish twice a year. Most seem to try to limit it to once a year. Three weeks ago, I polished my car for the first time with my UDM. I only used a light cutting pad (Orange 5 inch Lake Country CCS Pad) with a rather mild compound (Optimum's Compound) and I was able to greatly improve my light scratches/deep swirl marks but not remove them due to my car having such hard clearcoat. I also cleaned up that compounding using a finishing pad (White 5 inch Lake Country CCS Pad) and a finishing polish (Optimum Poli-Seal). Because I have some swirling left over and I hope to improve the scratch marks even more, next spring I will be moving up to a medium cutting pad (Yellow 5 inch Lake Country CCS Pad) and a more aggressive compound (Optimum HyperCompound) to try to complete the job completely. Had I removed the swirls completely and made the scratch much less noticable, next spring I would skip polishing and only wash/Clay/All-In-One/2 coats of Sealant.

Also, thanks for the clarification about the prep work

.
Many of the more experienced Autopians will swear that your prep work is far more important than the wax/sealant you use.

Now, let's say I want to have at the SUV again, but this time with all intentions of fixing imperfections with a PC or UDM. Would I need to do anything to remove the coat of wax I applied? Or would a wash and clay be enough?
Most on here will say no but I guess I am anal. Before polishing, I like to remove the old wax/sealant. Three weeks ago when I polished my car, here was my technique:
1) Friday wash car with double strength wash solution to remove any loose dirt and contamination.
2) Wash car again with double strength wash solution to ensure I had removed any loose dirt and contamination and clay areas I had just washed using the soapy solution as my lubricant.
3) Use Paint Cleanser to remove my old Meguiars #20 Sealant and to deep clean the pores of the clear coat
4) Wash car again and apply touch up paint to chipped areas and then put car in the garage and call it a night and let the touch up paint dry over night.
5) Saturday morning, wash car, use my UDM with the Orange LC CCS Pad with Optimum Compound. Because it was a cloudy day and I did not have appropriate lighting, I could not see the swirl marks I was leaving behind. However, the swirl marks were greatly improved.
6) Use my UDM with the White LC CCS Pad with Optimum Poli-Seal. My paint was so hard that it probably did not need the Poli-Seal to clean up with. However, Poli-Seal is a unique polish in that it can act as your All-In-One also. Therefore I was able to skip my Jeff's Werkstatt Prime Strong as my All-In-One and go straight to my sealant (Jeff's Werkstatt Acrylic Jett)
7) Apply a coat of Jeff's Werkstatt Acrylic Jett. Put car and garage and call it a night and allow the AJ to cure over night.
8) Sunday morning, wash car, apply another coat of JW AJ.

Speaking of which, being I just clayed the ENTIRE car, would I need clay it again everytime I apply polish and wax? Or should I only clay, say, twice a year, even if I plan to polish quarterly (if not more?)?
I would always clay before polishing. Getting the contaminants off the surface of the paint will make polishing easier and more effective. I mentioned polishing a car quarterly may be a little over kill; claying a car quarterly is recommended. Many on here clay monthly or more. I personally go with quarterly.
Now, being that you just clayed the car, do you need to clay it again before polishing? Kinda depends on how soon you polish it. I would use a simple test. After washing the car, run your hand over the surface of the car, particularily the horizontal surfaces (hood, roof, rear). If you feel tiny bumps, that means new contaminants have bonded to the surface and should be removed with clay.

Thank you again, buddy. You've been a big help!
No problem and you are very welcome. Again, I cannot stress reading more on this site. When I joined the site in July (I didn't even know what a clay bar was then) I would read about an hour a day. You can look at my posts and see I asked numerous questions when I was not able to find a specific answer to a question I had by doing a search on the site. When you are reading on here, focus on the threads in the DETAILING AND FINISH CAR section of the site. It was the most informative section for me.
