Hi everyone! Anyone have experience with Sydney Peak coping? We are having it installed next week as part of our pool remodel and the PB just dropped a pallet off. This stuff has rust all over it. Should I be worried about it staining the new white quartz plaster that they are going to install? Also, it flakes a bit so I am not sure if it is suitable for a SWG. The masonry guy said that it will be fine with salt and won't need to be sealed. Any thoughts?
