Got to agree, plugs are fine if used under normal circumstances, I fixed 3 punctures for my pensioner neighbours, Pat with her Hyundai Accent was quoted $40?
I said i would do it for just a "thank you" took 30 mins, only because I took the wheel off, I can't work lying down, have to push downward due to my spinal issues, anyway she spent the money she saved on a plug kit and a cheap air compressor!..win, win all round.
