Stopped a slow leak on my van tyre.Tyre was going flat very slowly, over a week.Put half a tin in my van tyre and half in another car that had the same problem.Both are holding up well after 2 weeks.Make sure your tyre is flat before putting it in.Can make a mess but cleans up easily

Has worked well for me. Flat tyre. Used product. Inflated tyre well. Always keep one in car now.

Been using this for years on tyres always works well ,remember to turn the can upside down when using it ,try have the puncture at the top of the wheel so the foam doesnt leak out while your stationairy (some will anyway) then drive straight away so the foam liquid can spread around the wheel and set ,if it doesnt work, the hole is to big or you didn use a big enough can for the size wheel you have.

Tldr; Does the job for small, slow leaks. 3-4day = 1.5-2bar loss.I had a very small leak on a 18 inch tyre, I chose the medium as the tyre was low profile-ish, so the volume within was reduced. It was so small I couldn't identify the leak area, and the tyre held workable pressure for 3-4 days.With tyre pressure at around 1.5bar, I used the entire can as instructed, this brought the tyre to about 2.4bar. I topped it up to about 3bar, thinking I'd loose a little pressure before it sealed. However, as the can is aerosol, it cools when in use, so expands when warms. This happens when you drive as the tyre gets warm, and so I ended up with a tyre pressure the next day of above 4bar steady. It had sealed quickly and increased pressure. I vented the tyre back to normal pressure, and haven't had a problem since. It's held up for two months+.Would recommend for small leaks. I would think anything like a nail would require a plug repair. And if on tyre wall, the tyre has to be replaced.But, it may save you in a pinch for again, small, slow leaks. If your tyre looses pressure within 12hr period, I'd say this is 50/50. Above that and you've got a good chance. Below that and the leak is too fast, indicating a larger hole in the tyre.I don't often recommend must haves as everyones requirements and abilities are different. But this works well for what it was designed for, it's relatively cheap, lasts a while in storage, and is the size of a can of hairspray.

Easy to use and life saver for a female to get her to safer point

Created a mess, most of it came out the joints. Disappointed

This isnt a product I've needed to use yet, or a product I hope to ever have to use but something I feel is essential to have in the car in case of an emergency. All seems good looks okay and like it will do the job. Hopefully never will be needed but good to have in the car in case.

Have not used it yet (hopefully won’t have too) but gave it 4 stars for price and delivery
