I would never use a scissor jack to raise any part of a car off the ground unless it was an emergency. I would only use it here to give me some fender clearance to feel the tire. These are the two items I put in my bag for tire repair and they are based on multiple reviews. I used the plug kit on my Infiniti a year ago to fix a hole made by a screw and have had no issues with it. The liquid will seal up to a 1/8 inch hole.
