I was asking how many pads because I just don’t know if one pad would do a whole care.

Trying to use a single pad on a car might work, but the pad will suffer.
Also, if you're using a FREE SPINNING, random orbital polisher, that is NOT gear-driven, then the WETTER or more SATURATED the pad becomes as you work around the car, the WORSE it will rotate and oscillate and this means you're simply spinning your wheels, or more bluntly - waiting time.
If the paint on this car you want to machine polish, and you want to do ONE polishing job, that is go around the car ONE time with some kind of polish or cleaner/wax, here's your process.
Step 1: Wash and dry car.
Step 2: Inspect paint using the Baggie Test - if you feel little bumps, this means the paint has bonded contaminants and the best way to remove them safely is via a fine grade bar of detailing clay.
Step 3: Do a Test Spot - see video already shared.
Step 4: If you are able to dial-in a process to one small area and it looks good to you - stop here.
Step 5:Tape-off any exterior pebble textured, black plastic trim. If you stain this material with polish or wax in my opinion and experience - you will NEVER remove it visually 100%. This means you'll get to look at stained plastic trim the rest of the time you own the car.
Step 6: Buff out entire car - start at the top then work your way down and around. If this is your first time - I STRONLY recommend tackling ONLY the HOOD or FRONT CLIP (hood and front fenders). This way you'll see exactly what you're getting into without becoming disappointed that it takes so long. If you try to do the entire vehicle in one day - your first time - from start to finish, it's going to take you 8 to 12 hours. Just depends on how fast your work and how many breaks you take.
Please take my word, just tackle the front clip or the hood the first time. If you start early, you can be done by early afternoon. You won't get burnt-out and you won't be dead-dog-tired. You'll also have time for a shower and relax the rest of the day. (this advice is in my second book, not sure if it made it to the third book).
How many pads to use
If doing just one buffing step to entire car - the plan on a minimum of 4-5 pads. In a perfect world, you'll get the best rotating and oscillating action out of any type or brand of free spinning, random orbital polisher when using DRY pads. As a pad becomes wet with product, and this is what happens as you work around the car, it becomes heavy and soft. It stops cutting like it did when it was dry and your polisher will STRUGGLE to maintain pad rotation and pad oscillation.
It's pretty easy to show yourself this, just pay attention to how well or how bad a pad is both rotating and oscillating on your polisher after buffing out a couple of body panels. Then place a fresh, clean DRY pad on the same polisher and watch and pay attention to pad movement. You'll instantly see better pad rotation and better pad oscillation.
Not sure if the above helps, but that's what I got.
