Review on 🔧 Outdoor Power Equipment Formula FlatOut 20124 Tire Sealant - Ideal for Lawn Mowers, Small Tractors, Wheelbarrows, Woodchippers, Snow Blowers and More! 4-Pack, 32-Ounce by Kenneth Wood

This product has only been fitted to my riding mower for a few days so I can't really rate its performance. I'm writing this for people like me who have no auto repair experience ie. I have never removed a valve stem. First, grab an empty bucket or a short step stool to sit on if you're my age, mid 70's. Each splint takes a bit of time and constant bending over isn't fun for the back. Then invest in a metal valve removal tool. The top of the bottle can easily break if your valve is really seated or if like me you're just incompetent. $2 will be worth it if you can't replace the valve stem. It will ruin a great day. Then use a jack to slightly raise the unit off the ground. This simplifies the installation of the valve, but most importantly, when the air leaves the tire, it doesn't accidentally lose its position around the rim. I didn't do that with the small front tires and it took some effort to get them back on the rim properly when re-inflating. And finally, be patient while pouring fluid into the tire. This takes time and you will need to periodically return the liquid to the bottle to release the air pressure. Oh well. I didn't get it right on the first two tires and figured that was all the tire was going to get. Drain the tank on the last two tires.
