John - good call and thanks for the feedback

- I was trying a much lighter / thinner mix of oil paints than usual on this kit to try and tone down the grain, the result being that I found it much more difficult to replicate variations across each panel as every time I swiped the brush along the panel it took more and more paint off, leading to an odd effect... I think next time I will just paint selected panels, let it dry for a week, mask, then paint the remaining panels. Overall (panels aside) I am quite happy though with the grain effect itself (seems more subtle than my prevous efforts) so I think the masking technique will be one I'll be trying next!
Mriccio - there is nothing too special about what I use to paint. Metallics are usually Testor's stainless steel metalizer with a bit of black mixed in every now and then, the wood grain is done using thinned mixes of Windsor and Newton oil paints (usually burnt sienna, yellow ochre, and black) streaked over the Eduard buff plastic. The metal work is my own mix of grey/green. A clear acrylic coat and a wash using thinned black oil paints to pick out the details. Nothing to it!
Cheers again guys! Still waiting for the oils to dry...
