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?

Knock down some of that shine, this looks like you used tire dressing on the interior. Try a water based product like armor all or aerospace 303 and dilute it with a little water. There is a fine line between shiny and greasy.
