Handline spool info?

I just came into possession of a handline spool during the Albion raffle. I have sanded it smooth and etched it with pertinent info. Now I am wondering what to use to seal and protect it from the elements. Also what is the reccomended size line and type to use?  Do i need gloves when fishing and what type should they be?  Also open to any other info that would be useful.
