Re:
Well, 2 steps forward and one back.
I managed to get the rear tyre to seal today.
I fitted a tube and got the tyre to 'pop' onto the rim and then removed the tube.
This left one side sealed and allowed me to add some fluid then inflate using the pump at the garage.
I then noticed fluid pissing out of a 4mm slit in the sidewall.
So, I've wasted hours of time, half a bottle of fluid and I'm back to having to put a tube in.
The tyre has only had a few miles through it so I despise the thought of binning it for such a small defect.
These are the type of tyre knicks I pick up on a regular basis, so I may have to ditch the tubless idea if it cant deal with this kind of puncture.
The front has held a treat though!
