thats the way buffing works, apply compound, smear it around with the pad then buff till it dries. Take a screwdriver and run it from the inside of the pad to the outside when its spinning to get the hard dried stuff off that will burn the paint. Then come back and lightly bull till it shines. Stay away from corners and edges.

enjoy

many a good paint job has been trashed with inexperienced buffers.

you wont be the first.
