Shake it up if it is still liquid it should be fine. As far as the prefect -it I use it for cutting new paint and sand with 2000 grit before buffing and remove the sand scratches with it so it should be aggressive enough for polishing an older finish. I use orbitals for polishing not buffing, circular machines for compounding. If the orbital will do what you want fine but they don't cut like a buffer.
