Review on 🚲 Panaracer Smart Seal Bicycle Sealant: 120ml (4oz) and 500ml (17oz) Bottles – Ultimate Tire Protection by Bill Kodba

I really liked this new sealant. I have been very satisfied with my Panaracer tires for many years. When I heard they made a sealant that was advertised to work great on their tires, I decided to give it a try. The natural walnut shell used here, rather than the plastic gloss found on competing products, was a key selling point. Unfortunately, they are also the reason why the product is not suitable for me. In short, the walnut shell particles prevent the sealant from penetrating through the valve core. They are too big and clog the nozzle pipe badly. I've tried this sealant on four tires. On one occasion I managed to pour about 2 ounces of liquid into a pair of tires after a lot of effort, spills and dirty floors and hands. Unfortunately, after a month or so, the sealant dried much faster than the Orange Seal Endurance I had previously used. The only time I've seen this work was when you poured a bead of sealant into the tire before installing the bead. until the end. This will likely work well on heavy mountain bike tires, but it's not a practical option for the ultra-thin flex tires I run. They are too unpredictable about installing the bead on the first try and have been known to spray sealant all over the place if I put it in and then try to install the bead with the supercharger. I need to use the valve stem method and unfortunately that is not possible. I recommend looking elsewhere.
