But the OP will probably only use it once. So that is $10 for the kevlar, and a whole container of glue, maybe $5 for a small container of glue. Then the repair might fail, and it was all wasted.
How much is a tire like that worth in the US?
To me it is false economy, particularly because you can't be sure it wont fail. Not to mention the time spent on it.
I always try to fix stuff first, before I throw it out. Sometimes I lose, but mostly I win. Cheapest Marathon is about $30 or so, given the tyre in question is still working ok, ie not bulging, a repair would be low risk.
