I have only done this one time. I branch fell from a tree in a wind storm from about 30 feet up. Went through the winter cover and through the liner in the deep end of the pools. It was stuck there when we opened the pool in the spring. The branch was about the size of a Baseball bat. I had prepared a zip lock back with play sand and also had a patch already cut. When ready, I removed the branch, placed the ziplock bag under the liner in the hole and then proceeded to patch the hole with a vinyl patch. If this is in an above ground pool, I wouldn't mess with it unless you think it is going to burst. Once you cut the liner more water is going to push out and make the sunken area even bigger. For above ground pools theres not a whole lot you can do. Maybe get rid of the moles....
You have no choice but to replace the liner

YES.
no on paint! You will need to replace the liner.
No
The answer is no. Vinyl liner pools and the concrete deck around the pool are constructed with "concrete receptor coping". The concrete deck is poured into the receptor coping which at the very bottom has was is called a "bead receptor". The vinyl liner at the top has what we call a bead, used to install the liner into the bead receptor. Because there is, and can be, only one bead receptor, a second liner cannot be installed.

Yes, replace the liner. Nothing can put the color back into plastic or vinyl or glass or steel.
There are a number of ways you could remove stains from worms on a vinyl liner. You could use cleaners.
To remove a fireworks stain from the bottom of a vinyl pool liner, first, brush the stained area gently to loosen any debris. Next, create a paste using baking soda and water, then apply it to the stain and let it sit for a few hours before scrubbing with a soft brush. Rinse the area thoroughly with water. If the stain persists, you can try using a commercial vinyl pool liner cleaner following the manufacturer's instructions.
