I'm sorry you have more than the usual irregularities. Some of what I see in the photos, I'm not really sure what I'm seeing - shadows?, mottling looking worse due to the lighting?, etc. In other areas, I have no doubt about what I see, and I wouldn't be happy with it either. It looks like you have several places that aren't nearly as smooth as they should be. I LOVE the color of your finish, so I hope it doesn't keep fading. I'm glad your builder seems to be listening. I guess it is better to wait for the winter rather than messing up your swim time. Good luck on all of this and keep us posted!
Keeping my fingers crossed,
Suz
