Hello sorry to keep posting, but before I picked up my bike I paid my shop to install slime as I keep slime kits in my cars. Many of the videos see talk about installing FlatOut - did I make the wrong decision?
FlatOut vs Slime

From what I've learned since slime first came out and since I started using flatout. Slime dries up / out in a few months. Flatout appears to stay liquid for much longer therefor working for much longer. Flatout claims two years, we shall see in time but so far so good. Slime works best on high speed tires flatout doesn't seem to care high or low speed. You use twice as much flatout per tire and it costs more. Personally I don't care as long as it works! I put flatout in my 26x4 tires back in Nov and since have seen my daughters cat use the tires as a scratching post and the flatout makes a little grey bubble about half the size of a paper match head on the surface everywhere a claw has gone through the tire. I have NOT had to add any air to the tires since I put the flatout in. That's about all I can tell you.

I was recently trying to buy flatout, and it can get a bit confusing with all the different formulas or variety's of it. The stuff I ended up with seemed very thick unlike what I used before, I guess it really doesn't matter as long as it works. I've also used a product called "Joe's no flats" https://www.joes-no-flats.com/ and I really like that stuff, thinner and easier to use.

I got this stuff locally because it was $2.99, and they had me with the words "Flat Out" on the can.
Did I buy the wrong stuff? I am sure that I'll find a use for it either way.
I may have to make sure that the tire has almost no inflation to make sur that I actually get some in the tube.
Any thoughts appreciated, thanks.

The stuff we refer to here is in a bag, and FlatOut is one word. I'm not sure if that's the same stuff, only pressurized, but the FlatOut we refer to here has fibers in it to help seal bigger holes.
Slime sounds like the original sealant, like what they use on tubeless bike tires. When it leaks out, it needs air to harden up, and the thinner the sealant, the faster it stops a hole up. I worry about tires getting heavier and heavier by adding more and more Slime over time.
It's worth noting that FlatOut seems to be marketed for bigger tires, like ATVs, dirtbikes, golf carts and lawn tractors. It's not much of a stretch to go to a fat tire bike. I put it in my city bike, with its 27.5 x 2.4" tires, but I don't know if it just adds too much relative weight or if it won't work in smaller tires.

This is what I have found that works very well in my tires.

Thanks - I , like Smaug, was concerned about the added weight but considering the bike is already 77 lbs, what was a few more pounds…but as he also indicated, apparently one application is not for life, so not sure how one determines when the slime or flat out dries out

From experience I can say slime appears to dry out in just a couple months and stops sealing new holes. The flatout in my tires now is still liquid after about 7 months and it's still sealing new holes. My daughters cat is still using my tires as a scratching post.
Ugh so I’m guessing when the time comes there is no way to remove the slime and replace with flat out? I’m assuming you just add the flat out? Lesson learned

Having taken many tires of all types off the rim that had slime in them it leaves a rubbery layer inside the tire and around the rim like poorly dried paint. It's about the consistency of a sun rotted rubber band. I haven't had flatout in tires long enough to have this happen yet or see the results....
From what I've noticed in 20+- years using slime it works to seal a hole when installed but doesn't do much for anything that comes after where as the flatout seems to keep sealing new holes for at least 7 months because the cat puts new claw holes in my tires all the time. Granted these are small pin prick type holes and just a small grey bead of sealant appears on the surface of these thin tires and I still haven't had to add any air.
Well, I’ll have my retailer inspect the tires after a few months - there’s the justification for getting that “unnecessary” 2nd bike! Lol

If you've got tubes, you could just replace those every spring and add new sealant and do a good tire inspection at the same time.

Personally I am ordering new thicker tires later this week. I will keep running the tires I have as long as they last BUT knowing how thin they are having backup tires on hand feels prudent.
I just got my first flat ,after 13 months , and there was definitely no " Flatout" left in it. ... Now my Aventon dealer is telling me they won't put flatout n bike tires ?? ..I think it has definitely helped , and only needed about 1/4 of the bag per tire. . I ordered a valve stem removal tool , but someone else put it in last time .so I have no practice at it. .Any suggestions ?

Air down remove valve stem core with it at about the 4 to 5 o-clock or 7 to 8 o-clock position push or screw the bag hose on hold it upside down and squeeze. If you got the standard 32oz bag put half in each 26x4 tire, if you have smaller tires cut the amount accordingly. put the core back in, air up and ride!
Make sure your rim stays centered in the tire as you air up.
