To clear or not to clear.....

So I went with the ever so cheap Rustoleum paint job on the Dakota this morning. Added a urethane hardener. Turned out pretty ok for a rookie. Slight orange peel here and there. Looks good at 5 feet and way good at 10 feet, so I accomplished goal.
Should I clear coat it or not? Do I wet sand before the clear or only after?
Going to be my daily beater.
