Target coatings urethane is water clear. and if there is a uv issue they also make an exterior grade that can be used as a topcoat.
Also, if you are staining what I like to use are the transtint dyes and I add a little to the finish. It gives a more even coloring
this is the reclaimed chestnut counter I did last spring. I used Targets conversion varnish with the catalyzer and a combination of transtint mission brown and dark brown walnut. Just a few drops in each coat goes a long way.
This is a yellow pine built in I did and finished with the Target urethane no dyes.
