Congratulations on finishing your SMR, it looks very good! I use Permalyn Sealer, too, not exclusively, particularly if I'm re-finishing something I'm likely to use Tru Oil or something similar. I like the way the Permalyn Sealer penetrates new wood. Anyway, as @smallpatch said, you probably should add some more coats of the sealer and then finish with a topcoat of wax. I've used Johnson's Paste Wax and Birchwood Casey's Gunstock Wax, both with good results.
