You bet. Only a trained expert should be allowed to patch a tire. I don't even know why they would sell those tire patch kits to the public. I always look for the diploma on the wall of the tire shop from the Massachusetts Institute of Tires.
I grew up in the construction business, trucks, tractors, equipment trailers, demolition jobs, and lots of flat tires. Plugged a bunch of them myself. Drove thousands of miles with heavy loads etc. I have a lot of faith in my own repairs, and in my ability to tell the difference between a tire that can be safely repaired and one that cannot.
OTOH, if a tire shop or service station made the repair and it subsequently failed and that failure resulted in an injury or property loss the repair station could be liable.
It's not "MIT" that decides if the repair station is capable, it's their liability insurance carrier.
Now back to the BC in question. Can it safely be repaired? Maybe, but only after examining it could I offer an opinion, descriptions delivered over the internet are a poor second to hands on.
Many BC's that have an inner bladder have no provision for replacement, and I would be concerned about slicing open the outer cover, any method used to close this slice is likely to become a new failure point.
I would recommend that the BC be returned to either the manufacturer, or to a manufacturer's approved repair station.
