Carbon fiber can repair?
 

So I seem to have a small hole worn through in my two brothers can. Does anyone know how it can be repaired? Do I get some carbon fiber and epoxy like fiberglass?

Yes I once helped a friend who was building a custom flush canopy for a racing airplane. I had previously worked with fiberglass and he basically did it with the mat and resin in the same way. I'd imagine cosmetically the repair will be visible but structurally you should be able to fix it.

Where is the hole located at?

It is fortunately at the tire side of the right can so not very visible.

There are lots of write ups on line. Look at the YouTube video of the guy repairing the CF surfboard and do the process in reverse from the inside of the can.
