I've had good luck with glueless patches (Park, Schwalbe, stay away from the cheap ones)

They work great as long as you clean and scuff the surface properly. One caveat, they sometimes fail when you put them on top of a seam. That's when the old glue-on patches work best. Problem with glue on's is, as we all know, that tube of cement is one and done, so the next time you go to use it, the cement tube will be bone-dry..

Also, in a situation like that wire coming through the tire carcass, I'll usually apply a glueless patch to the inside of the tire, too, (prep the surface like you would a tube.) and then maybe some clear silicone or shoe-goo in the cut to keep the tire from splitting

Glueless Patch. Wasn't he one of the Li'l Rascals back in the '30's?
