Used to pay the odd visit with fairy liquid, core remover, shraeder adapter.
Then I wised up and made a Ghetto inflator.
Just buy a fizzy pop bottle and be done with it.
I bring it to races with me in case I need to change tyres before the race etc. Has never let me down, even on tyre/rim combos that I had difficulties with at an old skool garage air line. I think the rush of air in is faster than the garage compressor, but obviously in a much less sustained style, but enough to get the seating started.
