Very good job. Color matching that blue is no easy task. Nice work around the inserts too.
Are you talking about the numbers on the inserts? I don't know why you would paint over them.
Or are you talking about numbers on the playfield? If you are, decals will be above the surface unlike the insert decals that would be flush with the surface. So when you clear coat it will take extra coats and sanding over the decal to get it smooth. So avoid the decals on the playfield if you can.
Great work.
