I built my tiki bar 2 years ago in my backyard in Maryland (Super hot and humid in summer, super cold and snowy in the winter, rainy the rest of the time), and used a spar urethane on the top. It's held up pretty well, but I do sand it and apply a few more coats every year. I think the top has around 15 coats on top now. It is possible to get a nice glassy thick coat on a bar top with spar urethane, but it takes time. You have to apply it with thin coats over the course of weeks. Otherwise it may not cure correctly if you use too thick of a layer all at once. Here's a pic of my bar top from last year. It's not very clear, but i've got postcards, copies of menus, as well as fake palm leaves under the many coats of urethane, and it's all smooth and level. Like I said, you just have to put on lots of coats over time.
