After using both the new classic and uk.. classic is definitely more user friendly and also leaves the paint finish smooth as silk where as uk has a bit of a grab to it even after I've removed it and let it sit for a few days.. not sure why but definitely two different animals..
note: the applicators used with uk will be stiff as a board and applicators used with classic not so much.. makes me think uk is way better even though corey says that has nothing to do with how it acts on paint.
