I'll stick with my homebrew Stan's-like sealant. No issues. I don't mind the latex sealants that need refreshing/maintenance every few months. My older homebrews that involved Slime, RV antifreeze (ethylene glyclol), and latex and it weeped like crazy from my old Specialized mtb tires (green droplets formed all over the outer casing). My homebrew (and Stan's) doesn't do this - I am curious about the Finish Line product...is it more like original Slime in terms of not needing to be refreshed/long lasting? My guess is "yes"; regular Slime never took-off as a viable tubeless tire sealant on bikes but was ok for filling inner tubes etc. to seal small punctures (and adding a ton of rotating weight). Keep in mind, tubeless-ready tires are not butyl-lined to make them air-tight so they need some sort of "smeg" layer to keep the air in hence latex sealants. This Finish Line stuff sounds better suited for UST applications (does anyone even use UST anymore?).
BTW - To my knowledge, there is no "solvent" in Stan's. Stan's is: liquid latex, ammonia, propylene glycol, water, and cornmeal.
