When first applied, the “Flat” coat will look like this. Make sure it is even, but don’t go overboard. Some modelers recommend several light “mist” coats—but for me one medium coat works well for me. I can see that I’ve gotten it even by observing the uniform shine of the coat that I’ve applied. I think one coat is enough—more coats just adds unnecessary weight. When spraying wings or stabs, coat one side at a time and let dry—preferably held in place on something perfectly flat like a sheet of glass.
