I already made a test with the colours of Revell, and it worked. I´ve planned to paint at least the r2-d2, but based on too many things to do, I did not start yet. By painting I did not plan to paint the whole figure, to ensure the metallic look - witch makes the models unique - will not disappear.Wow! I did not know that there were coloured versions available. However, I prefer the metallic look. But it should not be too difficult to paint them yourself.
