On a couple of occasions I've had slow punctures. Usually due to clumsy builders leaving screws on my driveway.

Something like this tyre inflator is essential kit for your car. I've had this one from OneAmg for ages and it's worked fine. There may be better ones out there, so click around and look for yourself.
