my 98 bmw 740il have some swirl on the body, i just try with scratchx today but result is nothing change, i start from a small area on the hood first, for at least 4 times apply in the same area with horizontal and vertical direction, but still no improvement, why?
is it just the bmw paint cannot repair by scratchx with hand, or other reason?
