Yes Pearl Clear is (should be) a readily available Tamiya spray - TS65. Since the Mica Blue already has a very faint metallic fleck through it, you shouldn't need to spray too much Pearl. Depending on how the Blue goes down (because no 2 spray jobs ever come out the same) depends on whether I spray 1 or 2 coats of Pearl. I generally aim for a semi-wet spray of the Pearl, so the lacquer isn't drying in the air before it hits the model.
