Hi,
I know a lot of people fill up their pneumatic GoKart tyres to prevent punctures but this weighs a lot and is expensive. I was wondering if anyone has tried something like this:

From what I've found on google it seems to only partly fill your tyres then makes a thin coat around the inside of the inner tube, if you get a puncture it then quickly seals the hole to stop the air getting out.

Not sure how effective this would be in a robot so thought I'd ask if it had been used before.

Thanks,
Max
