I have searched a lot but can't find the answer, can hand polishing cause holograms? Not likely, they are mainly caused by inexperienced/careless rotary users. And can you make the paint look worse if doing something wrong? YesI have many swirl marks all over my hood but only there, nowhere else.
Also tips for better results are always welcome
