I bought a pint of sealant at a LBS yesterday .
#stickershock
Took it out to the van, popped one bead of the tyre on, then most of the other one, grabbed the jug o' sealant and then the second bead popped all the way back off. So after putting the second bead most of the way on, I propped the wheel up so that the QR was kinda hanging on the second row seat and the bottom of the wheel is on the floor down by the sliding door track. With this setup I could hold the bead on with my left hand and right knee, grab the jug with my right hand, pour in a few oz's, put the jug down then pop the rest of the bead on.
Then I grabbed my floor pump and sighed, "this bead is never gonna set with a floor pump. But lo and behold. 8 strokes and CRACK!
