I ordered the resin to cast the wheels, but while waiting I wanted to experiment a bit painting the wood grain and see the results.
Started imitating the lines using a fine brush and Tamiya Linoneum deck brown xf-79,
Then I sealed using satin varnish so I can start with the first wash using black very diluted.
Here I experiment using filters of yellow and brown applied by brush, then another thinned black wash, and painted the metal parts.
