Just thought someone would like their CNC made with Aluminium in a had scatch free surrface with any colour they fancy.
I had the same issue, I ended up using Anodising First Choice Anodising First Choice - Hard Anodising, Soft Anodising, Colour Anodising, Chromic Anodising, Powdercoating, Electropolishing to remove my anodising as like other said, its hard to get hold of strong caustic based acids to remove anodising, especially hard anodising. They only charged me £10 and gave it a light polish over for free too!
