The rust mark will most likely never totally come out. It may lighten in color with age and may be bleached some be the chlorine. Consider it a permanent fixture.
Another new or used retainer.
No. Replace the liner.
Filter it then swim in it.
They don't make them for in ground.

Not financially sound. It would be better to keep the dogs out.
Remove the old damaged liner and install a new one.
I had an inground pool installed. We just turned on the lights at night and noticed footprints on the bottom. Can this be fixed? Call the pool company back. The bottom is normally sand mixed with cement. The liner will probably have to be removed and bottom smoothed. They should have checked that before installing the liner. Those printswi catch sediment and debris for the life of the liner.
YES.
It's certainly worth a try. I would use Aqua Seal or Seal All. -Both available in Walmart.
Yes, but it would be very expenses..
We used Garrett Vinyl Pools they have been around for years.
