Great results LRF4N
When my z was black I found it impossible to clean without adding little faint scratches and swirls was crazy. I use to do citrus APC through the Lance then power washed off,snow foam wash off,two bucket method with lamb's wool mits and the most suds ever then even let it dry without using a towel and the swirls still came up so gutted after it was corrected. Now I made a promise not to get a black car ever again due to how hard it is to keep looking good. I'm guessing black z must have the thinnest paint in the world haha
