It apeared to be really hard to get real mirror polish on them. actually i can't get them chromelike as i got the lips. Old aluminium guru from local metalworks said that some aluminium contains silicon and it won't polish really superfine, it leaves waterstain like small markings on it. And the dude was right, i have now worked with this centerpiece 8 hours with couple difrent styles and waxes and it just won't.
That's the reason why most these aren't polished but chromed. Problem here in finland is that this type of chroming is enviromental hazardous so chromeshops doesn't do it anymore.
