Anybody can do this if they take the time to do it right. The hardest part was making sure I had the right tools and liquids for the job.
As with any wax job make sure the car is clean. Good rinse off and thorough soaping. Foam guns work great, but the key is the right mixture of soap in the container.
Clay bar was easier than expected. I used the product from Clayzilla and had a problem the first time I used it. It scratched the paint. I took a couple of hours and calmed down then looked closely at the pad it uses. The pad has squared off edges at the contact side and that is what scratched. From that I learned to lift the edge anytime I came to a curve in the body so the flat section of the pad was used. Worked like a charm. It also removed a lot of minor scratches. I remember reading somewhere that it was slightly abrasive and my experience confirms that.
On to polishing. I used a Hex-Logic Quantum 5" Light-Medium Polishing Pad, White on the Porter Cable polisher at speed 3. I used the same method at the curved parts of the body so the edge of the pad wouldn't directly contact the "ridge" at the top of the curves. This I got from the video made by the man in Chicago who warned that the edges/ridges would wear much quicker.

Polishing was pretty easy. The toughest part was being patient and allowing the tool to work without any pressure from me. Just hold it lightly and let it do it's work.
To make sure the car is clean before applying ceramic I used 1/2 70% alcohol and 1/2 water to clean the car. After the initial rinse to start the project this was the easiest step. Make sure the car is completely dry. The alcohol/water mixture dries pretty fast since it's half alcohol, but I wiped it down anyway.
Applying the ceramic was easier than I expected. I started on the hood so I could easily see what it was doing. I did one quarter then while it was drying a did a second quarter like adjoining squares on a chess board. I had to wait a bit for the first application to flash (looks like a rainbow and it can hard see if the light isn't right). After buffing off the first area I did a third, filling in one of the other squares. By the time that was done the second area was ready. I also came to the realization that I could coat an area larger than 2x2 feet. For example, I did each door in one application. Again, after applying to another door (front/rear same side) and waiting a bit the first was ready to buff. By the time that was done the second door was ready. Took about 2 hours.
The second most important task with the ceramic is making sure it is all buffed out. It's easy to miss areas and looking at the car from all angles is important.
It requires a ton of microfiber cloths. I used the yellow ones from Costco. Bought on Amazon. And while I'm thinking Amazon if you have an account use
https://smile.amazon.com They will donate to a charity you designate for certain items you buy.
If I can do it. You can do it.
