Tire sealant that effectively prevents and repairs punctures. Customers said it "worked" even on old punctures and provided "1000 miles" without issues. Easy application once valve core is fully removed. Some report needing daily inflation but appreciated puncture protection. Also effective on other inflatables like footballs.

Remove Valve core and it is simple.

Ok, I've only just put this into my tires.
Because I'm a bit of a Wally I didn't fully remove the valve core before I tried to squeeze it in. After making a mess and sweating a lot, I decided to read the instructions. I then fully removed the valve core and it poured in easily. I have given it 5 stars because while I was being stupid I noticed that it set quickly when it came into contact with the air. I expect it to handle a small puncture easy. I'll change my review if it fails.

Definitely worth to put in.

Allowed me to ride a bike for 3 weeks before I got replacement inner tube. Needed to pump it up every day but saved me from walking 14 miles. The orange dots are punctures.

Easy to use

Repaired two footballs so far and still some left. My grandson insists the repaired ball is less bouncy now, he may be right, but he's having a kickabout after school, not auditioning for Man City first team, so it'll do fine.

It worked, on a five year old puncture!

I admit I was utterly sceptical about this product. I own a discontinued Giant Lafree Twist pedelec so plagued by punctures I put it in the shed five years ago locked the door and walked away. A bottle of this stuff was it's last reprieve, and, amazingly, it worked.
I put half the bottle into a 26x1.75 inch inner tube, inflated to 60psi, and went for a gentle ride of about 800 yards. I was slightly disappointed to find I lost 20psi after that, but came back, reinflated and this time gently turned the wheel a few spins, then left it a bit and tried again and IT WORKED.Only real downside is it came with absolutely minimal "instructions" on the bottle and nothing else. But YouTube is your friend ..
