Well been a few weeks since I waxed it I have to say still looks good with a basic car wash. Been throu lots of rain plus alot of pollen dust here in the south. Still can't see swirls. So I would have to say for a black car this stuff gets my vote.
My kids have black cars (Jeep & BMW) and they did both of them with this stuff this weekend and it does a great job & makes the car look brand new again. Wish this stuff was arounf when I drove a black car.
