There seems to be a chronic problem with the provided dispensing pump.
Size: 1 Gallon + Tool, Set name: Off-Road Formula
I looked at online reviews of the product performance and was impressed by its purported ability seal tire punctures. While the product may (or may not) perform well, the provided dispensing pump is pathetically unsuited for the application and it is impossible to clear the pump once the material clogs the small dispensing port. Some of the reviews indicated this but i assumed that they were not very mechanical inclined customers. The product, by design, has particulates, of varying sizes, suspended in the liquid sealant. The port on pump is very small and easily becomes blocked with the sealant and particulates that cannot be cleared; even when following the instructions to do so. It is very irresponsible for the manufacturer to continue selling this item with inevitable relative failure of the pump as this is the only way to get the sealant into a tire.

Good for ebike tires
Size: 1 Gallon + Tool, Set name: Small Tire/Bicycle Formula
Got it for my son’s older ebike that my wife rides now. He kept on popping tubes, maybe because of his weight. Anyhow, I fixed it up for my wife and put some FlatOut in it to prevent flats. Seems to work so far. Got the off road FlatOut for my ebike’s fat tires. Easy to add to the tires. The pump clogs up but it’s easy to clean. I will always add this to all tires moving forward!

Worked on slow leak… one month already!!!
Style: 18oz
Edit: Still holding proper pressure at 2-months !!!
Had a slow leak where my tire went from 44psi to ~18psi over 2-3 days… Dashboard light would let me know every few days that I had a tire problem and I would inflate the tire back up to 44psi… Anyway, I used this product and filled air back to 44 psi and it’s held the pressure for a month already !!!! Be sure to deflate tire to ~15 PSI before adding the product… it only took about 30 seconds to empty the container into my tire with the tire pressure low. Very happy with this product !!!
