How to paint ABS to look like wood I have a piece printed in white ABS, which is a half-scale replica of an unvarnished oak sculpture. After sanding off the worst of the layer lines, I'd like to paint it to get a nice wood finish. I believe that most hobby paints should stick fine, but how should I paint it to get a nice oaky appearance? Should I do layers of different colours? Will I get better results with spray or brush paints?
I found step-by-step instructions on Instructables specific to 3D-printed parts. In summary:


Sand and brush with acetone for a smooth finish (I guess the acetone vapour treatment would work as well.)
Prime with plastic primer
Spray-paint with a satin, nutmeg-coloured base coat
Add grain with darker, acrylic paint using a fine brush
