Thanks for your thoughts Mark.
I regret that I didn't apply movement to the valve whilst submerged.
The car does have a tyre pressure monitoring system (post no. 1).
The alloy wheel (and the car) is 8 years old so I wouldn't expect porosity.
When the bead sealer was applied the wheel rim had already been cleaned then refurbished by powder coating (post no. 1) so I think we can take it that it was as clean as clean could be.

Thanks Bill for this technique from your own experience with a mower wheel. Unfortunately the paddling pool's edge wasn't deep enough to submerge the wheel completely so I had to observe it in two passes. I also only had two hours (including dealing with a rusty scissor jack) as the car's owner had to depart for her second job! This BMW Mini wasn't supplied with a spare wheel either!
