Thanks fellas
The Silver dope is Modelmaster aluminium acrylic metallizer. The cowling and panels were polished aluminium alclad. The contrast is a bit too subtle. Over the top, the blue is Gunze Pthalocyanine blue translucent, which lets the cowling show thrue the translucence, a pleasing effect. Weathering is Gunze oil and smoke acrylic. The chips are with a silver gel pen, which I used to highlight the rivets aling the cockpit coaming too. I used Alclad brass dotted on every screw head for contrast!
