My guess would be, it won't impact the life of your liner. Like I said, I've seen liners with bleached out spots that were several years old. You asked if it damaged your liner; it did. But damaged doesn't mean unusable.

I cut my thumb about 15 years ago, and severed one of the nerves, 'damaging' my sense of feel on one side of the thumb. But, I continued to use the thumb, and it works quite well for most thumb-purposes. (At this point, most of the feeling has returned.)

Your liner is damaged, but not unusable.
