Wax: Good, Cover stick: not so much
My wife's black car had, what looked like, a key scratch down the front fender.  The scratch was incredibly shallow--it was hard to feel.  But being a black car, it the scratch showed.  The lipstick-like black cover stick or whatever its called, was useless.  It somewhat covered the scratches but didi not survive waxing.  It just wipes off.  The wax, however, is very good.  I think it did more for making her black paint look better.  Didn't get rid of the scratch but shined up very nicely.  Mind you, all scratches are not equal, but this scratch was very very shallow.
