I did this model. The modals all say "Modeled In Color" so I didn't do any painting.
Just sanded the joints smooth and used the decals. Then a bit of weathering.
I rather like how it turned out.
Here's my models page gerry1of1.wordpress.com/.../vulcan-shuttle
I also like the kit comes with magnets so the shuttle can seperate from the warp sled.
Nice detail, that.
