just an idea but could you melt a candle above it. The wya goes hard. Machine throught that. Smear the rest in grease so that the paint will not stick. They after machining. Spraypaint. Let it dry,. Then wipe of all the grease and wax. This should leave the paint in the machined part, maybe!!!
Just scratching my head having a quick think.
