So I did the baggie test after I clay barred the whole car.

OP, as you are claying, use a good amount of lube and continue until you feel the clay is siding very easily. Also most of the time, the sound will change as you clay the surface, it will start out sounding very scratchy (depending how bad it is) and progressively get quieter until it goes it away. Follow up a polish and always wax or seal the paint after you clay since claying will remove the existing protectant. And always, make sure the car is washed thoroughly before you start claying.
