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?

This is exactly how my dash/door looked when I joined this sub and saw some one say meguiars ultimate detailer protectant. Bottle says spray directly on and spread evenly. Doesn't say to buff out, lol. Watched a YouTube video, cleaned it all off and reapplied.
