Amazing stuff
Style: 14oz
I’ve been using this stuff for a number of years for a number of vehicles now and it works every time. It’s especially great with those small annoying leaks where you just lose a couple pounds every few days so you have to keep adding air like once a week. It totally seals it. The bottle says to only rely on it for 300 to 500 miles and then get a proper fix. However, I have not found this to be the case. The seal holds for the rest of the life of my tire every time I’ve used it. My only complaint is that I wish it was a little cheaper, but you can seal up 2 tires (use only half the can per tire - you can probably even get away with using less). There is a garage not far from me that fixes leaking tires for $10, which is the same price as this product so not really saving any money by using it. It’s more just a matter of convenience. Just make sure you get this “thru-core” one. They have other ones as well so it can get confusing, but the one you’d want for situations like I’ve described above (small to medium leak in a typical passenger vehicle) is this “thru-core” one.

Saved the day, even at 25°
Style: 18oz
The tire tread was peeling off the tire causing a leak that could not be plugged. Completely flat. It was about 25° outside and the can only dispensed half the contents. Was able to inflate the tire and make it to the shop. So the slime saved the day.

My new go-to for roadside emergencies.
Size: 58pcs, Size: 58pcs
Okay, I recently picked up this 58-in-1 tire repair kit, and I'm really glad I did. I've always been a bit nervous about getting a flat tire, especially on a long trip, and this kit has been a huge relief. The first thing I noticed was how complete it is. It's got everything you could possibly need, from the T-handle reamer to the solid pliers. I really appreciate the feel of the tools—they're not flimsy at all. The handle has a great grip, and the spiral tip on the reamer looks like it will make it easy to clear out a puncture without a lot of hassle. The plugs themselves feel tough and durable, like they'll actually hold up. I haven't had to use it on the road yet (thankfully!), but I did a practice run on an old tire I had. The instructions were easy enough to follow, and the whole process felt manageable. The best part is how compact the entire kit is. It all fits neatly into a little box that I can just toss in my trunk. It doesn't take up any space, and it gives me a real sense of security knowing it's there. It covers so many different vehicles, too, which is a nice bonus. It's definitely a peace-of-mind purchase that I'd recommend to anyone.
