The name boards look very good. If you're going to mount them on the sides of the flying bridge it's a good idea to place nylon spacers on the mounting bolts between the boards and the fiberglass (or wood on a wood boat). If you don't, moisture will become trapped between the boards and the sides of the flying bridge and will eventually get under the finish and start to lift it. It will only be a matter of time before the finish on the edges of the boards will start to lift, and then the fronts, and you'll be looking at a refinish job again. The spacers don't have to be thick, just enough to keep the backs of the boards free of contact with the fiberglass or wood underneath.
The same thing applies to name boards applied to a transom.
I made new teak name/nav light boards for the flying bridge when we bought the boat as well as new name and hailing port boards for the transom. The advice about the spacers was given to us by the shipwright who did a lot of work on the big GB charter fleet in our marina. On the transom boards he advised us to glue a pair of spacers, top and bottom, to the backs of the boards in their middles to hold them evenly off the curved transom planks--- the boards are bolted only at their ends.
If for some reason you don't want a spacer gap between the boards and the surface they're mounted on, then a smart thing to do is to bed the boards with something like Dolfinite. It comes in natural (tan) and white. Dolfinite is not an adhesive so if you have to remove the boards for some reason in the future they will come off easily, as opposed to using something like 3M 4200, Sikaflex, etc. (And for God's sake don't use silicone.) But whatever bedding material you use, the object is to prevent moisture from getting under and trapped behind the nameboards and attacking the finish because once moisture gets under the finish in the back it will eventually work it's way around to the front.
