So Far, No Flats

I put this stuff in my Ebike. I live in the country and drive on a lot of dirt roads with rocks. Haven't had a flat yet. Only time will tell, but it seems to be working.
It really worked

I put this stuff in as directed and 5 days later got a flat via big nail. It was flat. Pulled the nail out and pumped up and it held and continues to hold. I am happy with that. Issue: once applied its hard as he'll to add air as it seems to clog the valve too. You can do it but you will ring adding air difficult and measuring pressure will be tough. I would buy again and do again though.
Good stuff.

I haven't used this yet, but I have it when I decide to put it inside the inner tube.
If this is the same sealant the US Army uses, it HAS to be good...!

I had a flat in my E-bike rear tire and could not find anyone to change the inner tube. Tried this and my flat is gone! It was easy to get the valve stem inner piece out using the tool. Squeezed goo out of bag into tire. Replace the valve piece. Inflated tire and all good. It's been weeks now and no more flat!
10 STARS IF I COULD

i dont normally write reviews unless a product is really bad or ASTOUNDINGLY good. This Flat Out product is ASTOUNDINGLY GOOD. I would give it 10 stars if i could. I commute 10 miles one way to work daily on my ebike, this morning my rear tire was a little low on pressure, but i didnt think much of it, i pumped it up a few PSI and off i went. During start of the ride i heard the "Click, Click, Click" of what i assumed was a small rock in the tread. 8 hours later after work the tire was a few lbs low again but nowhere near flat so i investigated. I found a drywall screw 1.25" by 8mm in my rear tire! Amazed i "unscrewed" the screw out of the tire. The tire sputtered a bit of the Flat Out from the innertube and it sealed before it went flat FROM AN 8MM SCREW. I pumped the tire back up to 22psi and rode the 10 miles home without incident. Likely will not even have to patch it in the traditional way. If your undecided about whether Flat Out works, i assure you, you wont be disappointed. Worth its weight in gold for me, i will never ride without it!!!
