This evening after getting back from my regular Sunday practice session, I did a bunch more sanding of the RR2V body then wiped the dust off with some white spirit.
Once it was dry I stuck some plain Danish oil on the top. It seemed to suck this up pretty quickly so I've gone ahead and done the whole body a couple of times. The top seems to be going quite a nice colour although experience shows this will be lighter once it's fully dry. Putting the oil on the sides is really helping to bring out the contrast between the layers.
I'll keep at this the next couple of days so it should be ready for reassembly by the end of the week.
