• @Browndonneur It was sealant! Muc-off no puncture sealant, which is fine but not exactly the ultimate puncture fixing that it claims to be.
    @Hulsroy I just checked, it is the right way around but in your defence it looks wrong from the images, as the 'shoulders' have an angle to them.

  • That sealant is tenaciously sticky once it dries. I had to resort to a solvent after a great big glob of the stuff stuck to the back of a seat tube. My preference is the WTB stuff these days, though all of the pale milky ones are much of a muchness.
