I have a couple of the Italian sets, and just used some off the Macchi 205 set. I have to say, these are some of the best I've seen, almost non-existant carrier film, really solid opaque whites, and settle down with just a touch of set-sol.
You do have to watch out for the color call outs though, for instance alot of, if not most, C.202s and 205s had the upper camoflague wrap around the fuselage, and just the lower wings and horizontal stab were gray, but the Sky Models sheet shows every option with the full undersides in gray.
