So i will be replacing my valve cover gasket soon which requires the removal of the intake manifold. While im going to have the intake manifold off, i will be attempting to mirror polish it like the picture below. Does anyone have any tips or suggestions from experience they can add? so far i know i need a grinder, variety of sandpaper grits, wet sand and polish at the end with mothers aluminium polish or something. Anything else?

Thanks
