Depends on what your definition of "good" is...longevity, killer looks, user friendly, works on every paint in every environment...none of them have all of these qualities...so pick your poison.
I picked up a gallon of this back in February at advance auto on clearance and wasn't expecting much but it surprised me. it is sort of like Meguiars #26 wax in a spray form, or at least that is how I compare it. lasts a couple weeks and the beading was excellent.
