Definitely follow the directions. It goes on unlike any other finish I've used. I can't speak to it's long-term wear, but it made the surface way smoother and gave it a slick feel. It increased the sheen as well, but without looking plastic. It does indeed significantly increase it's ability to repel water, which is the main reason I bought it. The table that I put this on will be in a household with kids. This should help defend the top from those little monsters.
