Anodizing is an electronic/acid process where the surface material is oxidized and forms a harder surface. There are different types of anodized surfaces with different hardness. Anodized finishes are translucent so color defects will show up. Painting deposits a layer of material on the surface. It would need to be applied equally all around as to not affect the balance of the platter, correct? Powder coating would be better a choice over rattle can painting since a powder coat is an even layer and it is much stronger than paint.
