Slime Smart Spair Emergency Tire Repair Kit

I'm on vacation in the mountains about 30 miles from the nearest tire repair center. I got a screw in one of my brand new Conti tires (not in the sidewall). I expected my relative to bring a jack and lug nut remover from Autozone like I asked, but instead, he brings me the "Slime Smart Spair Emergency Tire Repair Kit" from Autozone.



Does anyone have any experience with anything like this product? Would I be doing more harm than good to the tire by using something like this?



I called AAA because I have a Plus account with them and they said their 3rd party service up here in the mountains doesn't patch tires on-site and they would have to tow the car to a location which they couldn't tell me where it was going to be towed, so I cancelled the service call.



Should I just get someone to help me remove the tire, get a ride over to a real tire repair shop to get it patched, then place it back on the car?



Here is the kit in question:
