A relative used to have a bike shop and sold stuff called 'slime'.

The car-tire places will mend a puncture on a wheelbarrow, no
problem. Keep the bits well greased, though, as it may be some years
before you need to get the wheel off, and it's embarrassing to find
the bearings are rusted in ("Guilty, m'lud!").

I don't know about makes, but if it's to be a special present, splash
out on a heavily galvanised one from the builders' merchant. The much
cheaper plain black-painted ones are OK if they live in a shed and
are kept clean; but they're unlikely to become family heirlooms.
