Congrats on getting your car. Test the little compressor to make sure it is OK (not full of goo). Assuming it is OK, buy a good tubeless tire repair kit and forget about the expensive goo. I carry a cheap repair kit that has long rubber strings and an expensive mushroom plug kit (like the one I carry on my motorcycle). The mushroom plugs make a permanent repair of a nail or screw hole in the tread. The strings and glue from the cheap kit can be used for a temporary repair of a larger tear such as in the sidewall (hopefully lasts long enough to get to a tire shop).
