How do i remove water spots?

PW370z

I had really bad water spots from my sprinklers. I just did this yesterday (or at least most of it, as it takes a long time doing it by hand. It may be faster with a buffer though). First I washed/dried the car. The I used Chemical Guys Water Spot Remover, then I used a clay bar, then the water spot remover again, then the clay bar again, and finally a coat of cleaner caranuba wax. This removed 99% of the water spots. It may seem like over kill, but these spots were really etched in, and after the first round of water spot remover/clay bar, the water spots were still fairly visible. Therefore, two treatments seemed to do the job.
