My vinyl liner feels like sandpaper

Welcome to the forum :lol: Likely calcium scaling but it is impossible to tell unless you can post test results from your pool water.
Welcome to TFP 
- Dave is right, it probably is scale... if you click on the Pool School button on the right side of your screen you can start there, but we do need to see test results:
FC
CC
TC
PH
TA
CH
CYA
If you don't have your own test kit - you can take a sample to the pool store and ask them to test it for you. I wouldn't buy anything from them yet, just get the results and post them back here.

Welcome to TFP!
You can also use the very inexpensive HTH 6 way test kit from Walmart (NOT THE STRIPS). You won't be able to get a good reading on the FC above 5 and only 2 CYA tests but it still may be more accurate than the pool store.

Pool stores test results are frequently terrible but they usually do OK on pH testing. Your VERY high pH of 8.2 would indicate calcium scaling. Lower your pH down to 7.4 right away using muriatic acid.
Calcium scaling is usually very difficult to remove. That it's on a liner may be helpful. Search "calcium scaling" on this forum to learn more about it and what you can do to remove it.
Never let your pH get above 7.8

I agree with Dave - I would get the PH temporarily down to 7.0 or 7.2 even. Use the Pool Calculator to determine how much muratic acid that is. Let it circulate for awhile and start brushing the liner with a vinyl brush, hopefully the scale is fresh and will start to dissolve. Don't be surprised to see that CH number climb back up as it is dissolved back into solution off of the liner (if it works.) how old is the pool?
Seriously consider your own test kit... there is are several articles in Pool School that you will find helpful.

Darn still pretty high according to my Taylor test kit still around 7.8.
I added the acid straight to skimmer is that ok or an ole Darn???

The skimmer is probably not the best. In front of a return will disperse it without having to go through the pump first. Still probably OK but use the return next time.
Dave was being nice -never put acid in the skimmer, risk of damage to the pump/seals/equipment.
How old is your liner?
Mine was feeling the same way, and I determined the liner was at least 12 years old. They only guarantee them for 10 years.
I just changed mine out.
