If its leather, the repair kits like 3M will work, but only temporarily before another area fails.
Best thing is just to replace the cover. They're not terribly hard to do. I did the whole interior on my TL with a kit from Auto Custom Leathers. He'll ship the cover to you and even include the hog ring tools if you need them. Good dude to do business with, and he will sell you just the cover you need (no need to buy an entire kit).

Yes, I did have a shop help with mine, but I'm confident I could have done it myself. The shop is my uncle and it was part of a trip to see family anyways, so why not have a pro help you out?https://autocustomleathers.com/
Not affliliated, etc etc. Just a positive experience.
