I have been polishing aluminium parts before anodising them with a coloured solution. The anodising process seams to spoils the reflective quality of the aluminium and looses a lot of the qualities of the metal surface - almost appearing plastic. I have tried a weaker solution with the anodising process but although the surface is more reflective it changes the colour - for example red turns to pink. Is there another process I can use or any alterations I can make to the anodising process to to keep the reflective qualities and 'metallic' appearance of polished aluminium??
