You don’t want...

...to have to pull one of these out of your boot.

Lou picked up a nail in one of her tyres and totally flat. Her car doesn’t have a spare... instead a small compressor and this stuff which will seal small holes. Worked a treat to get to the type shop.

My bike runs with this fluid in all the time and has no inner tubes...if you get a hole it self seals and if a small one you never even know it has punctured. With bigger holes it still seals but the fluid sprays out until a seal forms. Makes a mess but with an air top-up good to go again
