My pool was replastered last season. Within a few months, this "feature" showed up:

The contract states that they're not responsible for visual imperfections in the plaster, as did the other contracts I got with other estimates, but this seems significant.

I'm looking for opinions on what I should do - go after the company, grin and bear it, or is there a way to treat the plaster to make this at least less noticible?

Thanks
