it really depends on the depth of the scratches. try a
pure glaze, a non-aio and see if that helps. but by the time youre done experimenting with all different products you could probably buy a pc and some polish. i would just get the
Polish Starter Kit from DI and the
PC Starter kit and have at it.
If your car is black then the nattys that comes with the polish starter kit is great, it really makes the paint pop.
