Be aware of the name! Should be wolf in sheeps clothing. The paint on my rocks started to peel and come off shortly after installed. The owner stated he would address the problem, but then mysteriously didn't return any of my calls and then avoided them all together. I would strongly suggest not using this idividual to do your pool rocks. Look else where to someone who has a positive reputation, exersices integrity, and does quality work. You've been warned.
