What is the best approach to restoring the wood wheels? What is the best process? What is the color of the stain? I noticed that on some of the restored 240s (see picture) that there is high-gloss finish. Did they come from the factory with such a finish? (My son took this picture of #33 of the 42 Nissan restored cars when it was for sale on the showroom floor at Peak Nissan, here in the Denver area 7 or 8 months ago).
