This stuff is absolutely brilliant. It seals punctures that other sealants simply won�t seal. If you use the replenisher every 90 days it continues to work as well as day one. Just remember to replace the sealant completely once a year and you�re good to go. If I could give more than five stars I would.
Like the theory but reality is just OK. Setup is a bit harder as you cannot inject it through the valve. Per instructions, Silca's replenisher needs to be added every 90-120 days. Don't ignore this and aim for 90. And buy the replenisher with your initail sealant as you will need it probably sooner than you think. At 105 days, I got a flat that did not fully seal. It was pretty small but not sealling. No sealant in sight. I put in a small Dynaplug and still not sealling. I still did not see any fluid coming out so the Silca sealant appears to have completely dried out. No just deminished but bone dry. I not have any Silca Replenisher but did have a 2 oz bottle of Stans on hand. I put in the Stans and the tire sealed almost instantly. I'm sure the Silca would have been able to handle this puncture - if it was there - but it was long gone in just over 3 months. In fairness the instructions do clearly say this is a possibility so I'm not upset. If I stick with Silca, I will have to start checking the sealant level monthly. On the fence as to if the extra setup and maintenance hassles and the cost are worth it.

The sealant ate the rim tape and caused failure. Company stated you need to use high tinsel tape? Never had this problem with Stan�s or the Orange stuff.
