I picked grey lueders to coordinate with our travertine patio install - new pool & patio. I didn't want travertine coping 1. because of price 2. I don't like that they have to be cut really thin to go around a curved pool. Now we have these lueders on our spa and 100% expected a smooth surface. Should I ask for these to be replaced? There are some around the pool with lines/pits, but nothing like this.
