Bought a Fi Q 15" used today and when I got home I noticed some small, minor scratches along the foam surround. There's cat hair stuck to the enclosure felt so I assume a cat scratched , not directly, but when it when climbing up on top of the enclosure while it was in his house.

 

It's just a few millimeters deep in about 3 or 4 places

 

Should I try and patch it with glue or is it probably harmless? 

should be fine as long as it isn't punctured all the way through, there's multpile layers of different materials in that surround body the outside one for the most part is cosmetic

Thanks a lot, Nick. I figured as much, but wanted to make sure before I start putting power to it. 

If it delaminates you can either throw some 'amazing goop' on it or this stuff called e-6000...and if you don't want it looking like it will look after you do that a recone will always fix it
