I use the stuff all the time in ATV , golf cart , lawn mower tires... and I love it !! I had a difficult time with a couple car tires ,, and it did the job. so I have it in gal jugs
recently, I was talking to a vendor who sell the stuff.. and they just made a huge deal where as 2 large automotive makes have bought a small compressor / slime kit that can take the place of a spare tire.. so I forget which cars.. but they won't have a spare.. but a slime kit from the factory.
If I had a tubeless motorcycle tire.. and I couldn't find the leak to patch, then I'd slime it..
I found it difficult to squeeze it in thru the valve stem.... so I use a Vac pump to remove the air from the tire,, and I use a dollar store ketchup squeeze bottle with a short length of clear fuel line that fits over the valve stem... so I can watch it drain
