The thing about that finish, is that it does have a translucent wash over the whole body, but it can also have a subtle sprayed "halo" of the same colour around the edges - not quite opaque but less translucent. Below are example of both. Since you can't spray and if you wanted the halo, perhaps you can add one more paint layer there and blend it into the center. Should be doable.
with "halo" on 60's vintage - more translucent, possibly from aging
w/o "halo" on 80's RI of 60's vintage - more opaque
