Today when I went to Honda showroom for some service issues, they showed a demo of Seelin TL which is a fluid pumped inside the tube. It seems if you have any puncture, I'll block the hole and you even need not repair it!
They bought one vehicle and punctured it with a nail. After a while, they removed the nail and rotated the wheel. They said the fluid had blocked the hole and there was no need of any puncture repair.
Here is the website: SEELIN Tyre Sealant
Has anybody used it? Any side-effects?
