Review: #1 tire/tube sealant - #1 flat prevention/fixer. This stuff works so well and fast youll likely have trouble with it plugging up the valve stem when adding it to your tube, great trouble to have unless you enjoy flats 10 months not one flat i have lost 5psi a couple times but that was after pulling a nail and screw. With any other tube sealant i would have had to patch the tube but not with flat out. A must for fat tire bikes they love picking up nails screws tweezers staples glass but flatout stops leaks before youll notice youve got a problem.
Review: Very effective in general, love it for tubliss - I use this as a sealant in my tubliss dirt bike wheels. Always able to get a good seal after mounting despite having some old used tires with beads that are a bit buggered up. Also Does a great job sealing little punctures and is a great lube for mounting or when running low PSI.

### ⭐⭐⭐⭐⭐ Works as advertised, buy your own stem remover
*by A***T on January 4, 2026*

Amazing. Ran over a nail and got a flat. Applied patches, but tire was flat again the next day. Found a 3 inch ten penny nail completely inside the tube, ordered this product and it sealed every leak immediately.
