So here's a second car that I detailed with help from my friend, who owns this bimmer.
Black car is indeed tough to take care of, and even harder to do a proper job especially he never took proper care of it (never detailed, rough washing, frequent highway driving behind big trucks, etc)...
Hello, this is my first post... I've been doing some reading here but never posted before.
First time doing a full out exterior detail job by hand (no machine :(), and only had one small buffing towel.)
Still some swirl marks and oily surface as you can see on the last picture.
Any...
