About three years ago I refurbed a dark walnut steering wheel; I glued small split-offs, filled cracks with a colour-matching sanding dust paste and finally resprayed with 8 to ten coats of 2K-clearlacquer followed by patient wet-sanding and polishing. Many hours of patient work but basically possible with very good results. As opposed to this staining a light oak wheel to dark walnut will be highly problematic because staining wood requires a surface completely free of any residues of lacquer and that´s impossible with a 0,6mm thick veneer (provided that the light oak wheel actually has a real wood veneer like the dark walnut ones have). Alternatively it is imaginable to use a tinted clearlacquer instead of a woodstain but it is very difficult to match a particular colour and usually requires series of tests until the match of the colour is sufficently satisfying.
