Have you used the can that came with the car? Say so on the phone. Nobody is going to be annoyed about it, but the job changes shape completely and it is better known before we set off than discovered with the tyre half off the rim.
What is inside those canisters is a latex emulsion pushed in through the valve under pressure. Spun round the inside of the tyre it plugs a small hole in the tread well enough to get you off a dark road, which is exactly what it was designed to do. What it also does is coat the entire inner liner in a sticky film.
A patch has to bond to clean rubber, so all of that has to come back out before a permanent repair to BS AU 159 is even possible, and it comes out with water and time rather than a wipe. It gets into the sensor as well, and a sensor with dried latex across its port stops reporting anything useful. None of that makes sealant an enemy. It simply makes it a different job to the one you rang about.
Christmas Day, New Year, Easter Monday: the days when absolutely nothing is open are the days a tyre picks. It runs 365 days a year across Greater London, bank holidays included, at whatever hour the call comes in. The wheel comes off in Kew, not on a ramp in Twickenham. Nothing is towed out of Kew or North Sheen; the work finishes there. TW9 takes in North Sheen and Petersham, and we work the lot.

The streets running down towards the river and up around Petersham are narrow and dark in places, which is precisely the situation an aerosol canister was invented for. It is also a situation where somebody can reach you inside the hour with lighting, a machine and the correct tyre aboard. That makes the can a last resort rather than a first move.
A driver on Kew Road got themselves home on a can and rang the following morning. The hole was central, the casing was sound, and the tyre repaired perfectly well once the liner had been washed back and dried. It just took longer.
Sealant does nothing for a split shoulder or a cut sidewall, because there is no small round hole for it to bridge. Half an hour goes on pumping the can in and waiting for it, in the dark, before the driver rings anyway.
An older car near North Sheen carried a pressure warning that would not clear after a sealant repair the previous winter. The port was blocked solid. The sensor came out, was cleaned and tested, and the light went off for the first time in months.
If you are alone on a dark road and it gets you somewhere safe, use it and tell us afterwards. If you are on your own driveway with the car going nowhere, leave it alone and ring instead. Waiting costs you nothing.
Not by itself. A tyre that is sound apart from a nail hole is still repairable after sealant, provided it was not then driven soft for miles. What sealant ruins is the simplicity of the job, and now and then a sensor.
Yes, on the van, with the tyre off the rim. It is water, time and a good deal of wiping rather than anything clever. You will be told at the outset roughly how much longer it adds.
Frequently, once you count the sealant, the second can most people buy afterwards and the sensor that sometimes needs cleaning. There is no night surcharge here, so the hour is not part of the arithmetic.
