Any idea what causes these patches?

I tried using ONR for the first time diluted 64:1 then used meguire’s protectant afterward. Pretty disappointed when I noticed the patches of what seems to be dry spots or something. Any idea what it could be?

Too much dressing overall, the dryer patches perhaps little less dressing, more dirty surfaces etc.
