Anyone use this stuff? My wife picked up a nail yesterday in her RX330 and took it to NTB this morning. They told me the nail was to close to the side wall to repair...and we would have to replace the tire (nail is on the outer band of tread pattern). The tire is a $207 michelin (Ouch! ) and I was wondering if I pull the nail and use fix-a-flat, if it would seal the hole and work fine...it looks like maybe a 3d or 4d nail....so relatively small.
