I've been using a similar product called Amerseal for the past 5 years with excellent results, made here in the USA. I first found it at Rural King and used it to fix a heavy trailer tire. Since then, I have used it on tubeless and tube type tires on tractors, autos, lawnmowers, motorcycles, semi trucks, trailers and more with excellent results.
Contrary to other opinions expressed above, I really like this stuff and I highly recommend it. Prior to installing it in my new trailer tires, I had to check and fight trailer tires every 1-2 weeks due to punctures. When I put the new set of tires on, I installed the sealant on all 8 tires at the same time. I now check the air pressure on those tires with an air gauge 2-3 times per YEAR, daily with a simple thump test. This has saved me countless hours of wasted time over the past 4 years.
NEVER use Slime as it will degrade the rubber and often pit or corrode a rim. It is ammonia based and nasty.
Amerseal is water based and won't mess up the rubber or the metals. It can be washed with soap and water and then an inside patch can still be applied if so desired. I've managed to run several tires through a full lifespan using this method instead of trashing them due to a hole. Cleaning off the goo during a tire change is simple - use a wet rag and a garden hose to rinse it off. It's not as messy as some would lead you to believe.
I am currently using Amerseal with my Orange Tire Pressure Monitor sensors without any ill effects. I just can't add the sealant through the valve core of the sensor. Not a problem as I always add the sealant at the time of the tire change.
My tires run cooler and at a lower hot pressure with the sealant installed. I've also noted that the tires that were run without the sealant did not last as long so maybe the claim of cooler running does help the tires last longer. I got 2k fewer miles on the Anakee 2 that was run without the sealant than with the other 2 same tires with sealant that got 10K before needing retirement. No balance issues noted either as the sealant is supposed to help with the balance.
I found a place in Nebraska or Iowa where I ordered this stuff in 5 gallon pails with a special pump that meters the amount installed. Of course I have more tires to look after than the average Joe and I do all of my own tire work, no matter the vehicle. I'm sold on the Amerseal.
The time that really proved to me it worked was when, after changing tires on my former XR650L, I picked up a blackberry or green briar thorn that punctured the new tube on the front tire. It was flat in less than 24 hrs. I dumped the required amount of Amerseal into the front tube, aired it up, rode it 1/2 mile at most, parked it for 2 weeks and the tire never went down again. When I sold that bike, the tube had never been patched but the sealant did its thing.
This stuff may be snake oil for some, but for me, it saves me time, labor and money. Great stuff. ::008::
