Don't buy this kitten ultra No 1 polishing wax if you have a Black car! Thankfully I tested it on a small spot on the bonnet of my 2008 BMW 130I, which has the Black Sapphire Metallic Paint. I thought this would be just the thing to help protect and shine my car back to it's true beauty, but unfortunately it just left swirls, no matter how hard I tried to buff it out. I thought it scratched into the clear coat and left marks but I managed to wash it off and buff some of the swirl marks out. I would not recommend this product for Black Cars but I would recommend it for tired White Vans! It cut and polished my White Vans duco back to somewhat new. My Van's duco was a very dull chalky white but the Kitten No.1 bought it back to a brilliant shine, and no swirl marks! Very happy it could be used somewhere. Still looking for a Black car polish, the Meguiar's Ultimate Liquid Car Polish seems to do the trick on Black duco for shine but doesn't get the tiny scratch marks out. I need a product that helps cut and polish the tiny scratch marks out. Sadly this isn't it but if you have a dull white car or van, this is for you!
