fantastic, works better than i hoped.

i got this originally for my etrike wheels as cheap insurance,so far no problem no punctures, then i put in lawn mower tires one which leaked air over 1 month time went flat and my trailers tires one tire there went flat in one day, after i put Flatout in i forgot that i even had leaks in past , totally fixed the leaks, its funny that when you dont have the problem it took me a while to realize this worked, i will get the other formula for my other tires, a great product

FlatOut Tire Sealant is the ONLY sealant to buy

Have been using FlatOut Tire Sealant for years. Use once and it lasts - works where others fail. First time we used in the same tire nephew added inferior product that failed miserably. FlatOut sealed even with the other miserable goo still in the tire, and has lasted 5-years so far with no leaks. FlatOut is thick and has particles so it works, be sure to take the value stem out before filling the tire. - if you get a gallon, clean out the pump after each use (take it apart and use a hose wire tapping to clean out the pump). Cannot recommend FlatOut Tire Sealant enough - 10 stars

Do you ride bikes? Have small air filled tires?

Works well, easy to use instructions. Easy to install on the two bikes I used it on. Had plenty left for more applications if need be. I've put over 100 miles on a new e-bike fat tire that I recently purchased along with this product and rode this bike through all sorts of terrain and what not and have had no flats at all and I believe this product is the reason for that. I can't say for sure if I have had punctures or not but if so I haven't noticed. Highly recommend for bike riders alike.
