Hi falker;
I'm not aware of a process to fiberglass a liner pool, nor can I imagine how such a process could be successful. Liners tend to last 5 - 10 years, so yours may well be at the end of its life.
It's not likely that your pool lost that much to evaporation, but it may be possible in a dry windy area. But, you can test using the bucket method.
1. Refill the pool at least 8" above its current level.
2. Mark the water line, possibly with masking tape on the liner or ideally with a magic marker on a SS ladder rail. (Can remove mm with rubbing alcohol later).
3. Suspend a partially filled and marked bucket of water IN the pool (so surface & temp conditions are similar)
4. Wait a week -- if your pool has gone down farther than the bucket, you have a leak.
