New Prius Owner with Question

Hey there, just purchased a 2011 Prius 3 with Navi and 84K miles. Have only had it a few days and so far I like it. Still have to get used to the drive and figuring out what all in the display means.

I was checking out my spare tire area and came across this seal along the metal areas as pictured below. Do other Prii have this same thing? Or is this the result of an accident repair? Car rides fine and no accidents reported in Carfax. I did look at the car at night when purchased from Toyota dealer. Hopefully its not due to a large repair. Appreciate any feedback.



And here's a pic of what it looks like under the spare.

 

Thanks. I did a search but came up with nothing. This puts my mind at ease. Looking forward to learning more about the Prius moving forward.
