I used the green stuff, can't think what its called. It worked perfectly on a MEZ4 which lasted for another 3000 miles. I used the second half of the bottle on the new tyre. Came down to the garage one morning to find i'd got a puncture and a big pool of green slime under the bike!
The tyre people didn't like it either, makes the rim very slippery and its difficult to get the new tyre to seat.
