I use the next grade up the "bulletproof".
It costs a little more but I cant find it any cheaper than gemplers.
Anyhow, I have put it in my last two kubotas and a bobcat skid steer, pickup trucks before they started putting in the tire sensors.
They claim a 1/2" hole will seal or a .223 round, I have not tried shooting the tires but all else seems to seal.
Never had a flat or a leak since I started using it.
I usually buy the 5 gallon jugs and put it in all the stuff I have, think I have it in everything.
I improvise on their hand pump, I refuse to pay $200.00 to pump in $300.00 worth of spooge.
