Hi Hercmeck, unfortunately i can't really get into the specifics because I am writing an article based around this build for another magazine. However, I can say that the only pigment work was on the lower hull where the thick mud is and it was simply piled on dry, drizzled with paint thinner and left to set. The mud on the upper sides is done totally with oil paints, no pigments what so ever.
Thank you for commenting.
