Way Off Topic, Sliding deck door question

[got3fords]

The sliding door that opens to our deck as been opening rough lately. Several years ago I replaced the rollers, but now it looks like it's the track the rollers glide on that's the issue. You can see and feel unevenness. Is there a fix for this without getting a whole new door or ripping out the old track? Can something be put over the bad section?
