I'm a technician at a GM dealership, we use plugs, patches, and patch/plugs. You can pick all of them up at your local auto parts stores. If it was mine, I'd plug it. I have a plug in one of mine and it does completely fine. Legally, shops are no longer supposed to do plugs because DOT doesn't approve them anymore. A lot of customers don't want to wait to have their tires patched. If I do a patch, I go ahead and do the patch/plug, so if the patch becomes loose, the plug still holds. But, its like ice cream; Everyones got their own favorite.
