I have washed, clayed, polish (DACP and Meguiar #9), Klasse AIO, and now I am appling P21S wax. Before applying the wax my black paint had not swirls at all 
I applied the first coat of wax with my PC set a 3 with the finishing pad, and this morning when I took my car out of the garage I noticed under the sun that there were very very light swirls, I guess they were created by using the PC, or maybe because I should have set the PC at a much lower speed.
So, I have a couple questions:
Do you use the PC to apply the wax? if so, at what speed do you use it? Should I apply the second coat by hand instead? Will the second coat cover the very very ight swirls created by the finishing pad?
Thank you in advance,
