Review on MULTI SEAL 20110 Multi Purpose Fluid_Ounces by Kulwinder Hendrickson

We bought two e-bikes with fat 20" x 3" tires. FlatOut comes highly recommended and is quite easy to add to four tires. But the plastic stick wrench built into the cap broke immediately, almost stopping the operation (plastic fragments). Luckily I had bought an inexpensive aluminum bar wrench a few orders ago. After the stem was removed, adding 1/4 FlatOut to the latch went well. The built-in handset is awesome. Reinstalled the bars, carefully inflated the tires and made sure the bead was properly hooked to the rim. Do not rely on a flimsy stem wrench unless you have previously loosened the stem.
