Great update! Glad to see it running in video! Should be lots of fun.

I have it in all my machines including in the 60 year old military tires I use in the winter tires for my coot which are the most cracked tires I've ever seen and they haven't lost 1 PSI in 3 years.
When I bought some of this slime last it was pink seems they changed the look. Has like "hair" in it super good at filling leaks, only thing is don't pour it in the tire too fast or it will clog the stem, as it clogs any hole under pressure even a valve stem lol
