I recently redid a vanity for the wife and she wanted a new top made of walnut. i found some really nice looking 8/4 walnut that i milled up and made myself a panel. this is going to go into a bathroom obviously and i want to use something very durable and completely seal the top. is there a product you guys can recommend? i have thought about using something like how they finish bar tops etc. Ive also been told to use spar varnish the stuff they use on boats by a buddy. what does the hive think?

thanks,
Thomas
