I’m pretty sure I got these from a sprinkler so probably pretty hard water. They’re really only visible under direct lighting like this and not even noticeable in the sun. Car is covered in ppf and ceramic coating but I still couldnt buff these off with my detail spray after a wash. Didn’t try my chemical guys water spot remover because I heard someone damage their coating with that. Still have yet to try vinegar but I’ve heard mixed experiences with that. And I have CarPro Spotless 2.0 on the way. I know I haven’t tried much yet but wanted to know if you guys have any other solutions for these spots or etchings on ceramic coating? Thanks.
