To be honest, I've never had to use it to seal an apartment. It appears to be the same kit but with a different name that GM sells without parts for their vehicles. My Styrofoam trunk organizer Bolt has room for a compressor and cans of Schmiere. They fit in perfectly and match what came in my 14 Spark EV. While I'm sure it's not as good as a true stock tire, now that I've replaced my OEM "self-sealing" tires with better ones, they offer peace of mind.
