I didn't notice this before but recently when I was washing my car, I notice there were blotches of faint, dark stains on my car's white exterior.
They happen to be at the spots of where there was oxidation, prior to using turtle wax's rubbing compound to remove them.
Now it leaves a nasty mark on my white car's paint, kinda like fading acne marks.
Any solution to get rid of the marks? I'll post up pictures later.
