Umm, you can use gloss paint to make it nice and shiny, instead of semi gloss and then a clear coat.
Gloss paint is easier to wipe clean. Rustoleum to name one mfgr sells a line of home-project water-based paint that cures to be very tough. I used some on a doghouse roof 3 yrs ago (gloss), and it has held up perfectly outside the entire time.
Water-based paint will cure much faster than oil-based.
