Tamiya S13 Colour Mix Question

Hi All,

I'm seeking some help, and have a couple of questions.

My last car was a PS-13 Silvia (Q's), and I have Fujimi "Drift Kings" kit (of a S-13 K's). My plan is update the model to represent the Q's.

I want to replicate the blue/silver metallic paint of the Tamiya kit - does anyone have a copy of the instructions and would it possible to let me know what the mix is?

My second question is: has any manufacturer made a kit of the U13 Bluebird (Altima in the US)? I'm now driving a HNU-13 ATTESA, and am keen to track down a kit or die-cast model. My search has not been successful so far :(

Thanks in advance.
