stcat , I am trying to remember exactly what I did foe the prop, especially since I had to redo it and changed the method 2nd time around. It's harder than you think on lt because of the many many different things I tried for the plywood they all are a blur at this point.
I am pretty sure that was Tamiya wood masked off and the MM enamel Military Brown. The grain is done with Windsor-Newton Winton Oil #35 Raw Umber. Because this would have removed the brown I have to coat is with a clear flat acrylic. Easiest way is to just use all acrylics of the base but i didn't have any brown. Wipe on a thin film of the oil. This was then streaked with a piece of a Scotch Brite pad. Several coats of Future for the gloss. I didn't use clear yellow coz since the props broke and were changed out so often there was no time for the shellac to yellow like on the fuselage.
