When I used it, it was called Flat Proof and it wasn’t green and wasn’t an aerosol (Slime was unheard of yet)…
I used it in tube type dirt bike tires and it worked very well for its intended purpose and was worth the time and cost of using it…
Every time I replaced a tire I replaced the tube with it… the tire would have sometimes 30 or more thorn punchers it and never go flat…
The only other tires I use it in was a wheelbarrow and a couple of golf car tires that were tubeless… it worked well on them to, but I had no intention of reusing the wheels if they didn’t hold air, or having someone else service them…
Work or not I wouldn’t use it in my personal vehicles for highway use…
