David, that is testors model master Nassau blue metallic [28128] covered in testors model master ultra gloss clear [28139].
the additional coats of clear have really helped to get the look I am after, from the 3rd coat onward it really started to get the shine/depth I was after.
how long do you wait to start buffing/polishing? as it's lacquer it shouldn't take too long to fully cure, should it?
