Why would i laugh at you...
I myself started with cosmic, stayed at with one jar of turtle wax for one whole year and now im using meguiars.
I'm just trying to guide you that there are swirls on your car because you did not clean it properly previously. If you compound your car and don't correct your cleaning method, you will still get swirls again in very less time and a layer of clear coat would be gone. Eventually you will run out of clear coat and you will have to get a new paint job.
Sorry, i havent used Brill products yet so i cant guide you on their application.
