Conversation Between lavi rider and diomar

Dear Lavi Hi,
Sorry to bother you, but I've noticed in some photos you have published that you use some kind of paint for the wooden constructions you made. I am talking especially for the Carf J-10 thread. It looks like marble and its great! Could you share it with me? Either the color type/paint or the process you use to achieve this result?
Thanks again!
Best regards
