There is a bottle of tyre sealant which is screwed into the tyre inflator (compressor) which is then pumped into the tyre,once inflated to the correct pressure providing the sealant has worked drive for ten minutes and recheck tyre pressure.you must have a permanent repair done to the tyre although some repairers won't touch a tyre when sealant has been used.I certainly won't use the repair kit but will phone Honda assist to get me home,if Honda cannot provide me with a spare wheel and jack then I'll use the breakdown cover provided with the car rather than risk writing off a perfectly good tyre,also I wonder if using the sealant through the inflator renders the inflator unusable as it states in the handbook not to disconnect the bottle from the inflator after use,so what's the answer??
