Dss902,
I'd just paint the fairing. Use a good quality flat white enamel as a primer, that way you can apply a very thin coat to start with. Then, apply the next color only thick enough to give the depth of color you need and no more. Don't worry about the shine or gloss of the paint yet. If that's the final color, apply Future for a gloss, then decals, then Future again.
If you need to mask for another color, do that before you decal and overcoat with Future. This way, you end up with the maximum color depth with the thinnest possible paint thickness.
Cheers
