For the windshield, i tryed ordering it from tamiya france (T2M), who asked 10 euros for the tree ! So i tweaked and asked my lhs to order it. And they told him it was free ! So i'm waiting. Eventually i'll try making a new one from clear styrene, but i'll see that at the very end.
The brakes were painted with various paints, a mix of gun metal/alu (x-10/xf-56) for the calipers, humbrol metal-cote (27003) for the discs, and metallic blue (x-13) for the hubs.
