Hi,
Another quick question - we got a sample of pebblesheen and are wondering (in addition to all of the deep pits throughout the pool) about the variability across all of the finish. For example, the difference between the top and bottom of this picture (it's this way all over the pool). We sent our builder this picture (with the sample in for reference) and asked about this variation and the missing pebbles, and got the response that this type of variation / missing pebbles is "standard for pebblesheen" - this doesn't make sense to me, but I don't know pools and wanted to confirm.
