Good Day, I just wanted to let you know that all swirl marks on my dark blue Honda was removed, using the SF4000 only with the yellow polishing pad. I am extremely satisfied with this kit. Thank you for all your help and advice. Pity that so many people, including myself, get the wrong info by so-called car care specialist like the car care centre I took my car to, to have these swirls removed. I was simply told that it’s impossible to remove these marks and that it’s a feature of the specific paint. Clearly an answer given by someone who does not know or care. Luckily I was researching swirl marks on the internet and got hold of the crazy detailer site. I will certainly recommend you to anyone. Regards Fred Bezuidenhout.
