I've seen it done on a YouTube video but I can't do it.

I've done it with Caffee Latex but it is messy and requires a good bit of pressure using a large syringe. Also, more chance of the sealant gumming up the valve this way.

EUREKA!

If the sealant is truly up to the task then just use a massive needle to inject it straight into the tube. The sealant will close the hole.

What could possibly go wrong?

Here it is....

Pretty easy. I use it on our MTB tires and the kids bikes. I don't bother with my tri bike or me and the wife's road bikes. I agree with what he says about slime being not good on low volume high pressure tires.

Maybe I will try Stan's???

Just use Pitstop, it's made to be used with the core in and has a dry time of 3-6 months.

Tried it in the past as an emergency fix - complete disaster. Plus, it performed poorly in the shoot-out. I already ordered TLR - it rated best in the shoot-out.

So I'm being told that a 42mm Vittoria tube works with the newest Super 9 disc so this shouldn't be an issue.
