I used ShoeGoo on a couple of sets and it was OK but not brilliant as it can be peeled off as it doesn't bond to the rubber like other glues.

Gorilla clear isn't gap-filling as such, that's the light brown foaming stuff.

I bought a bottle of IC2000 but it went off very quickly and won't ever buy again.

The Uhu I mentioned was supposedly the stuff recommended by NSR a few years ago.

The Team Yokomo RC guys use 'Yokomo Omakase GLUE EX Instant Tire Adhesive'...it's not easy to find though but is for rubber tyres on plastic wheels.
