Does anyone know if this stuff should work on a current punture?

The description says apply BEFORE a puncture.

This suggests it is preventative.

Does anybody know of anything simular that I could use on a slow puncture?

Caps. thanks. i did see that. i`ll take a second look

The slow leak might be at the bead, unless you can trace the leak somewhere in the tread then plugs aren't going to help.

No, its supposed be in the tyre and seal a puncture when it happens. It certainly won't fix it if its not in there already.

In my experience, its pretty hopeless at fixing punctures even its in the tyre beforehand....so don't bother!

I've just had that with my front tyre - got it taken off, bead and rim all cleaned out, now ok.
I've got Puncturesafe in my tyres. Seems to make the wheels feel better balanced.

Mr Grumpy, I beg to differ and always use Goop. It's cheaper than the market leading brand Ultraseal, and it has definitely worked for me.
I have had a couple of occasions where a large nail has been embedded, and in one case must have been there a long time and neither time I was aware of picking up the puncture. Both would otherwise have been a rapid deflation. It was only a spot of green liquid on the drive under the wheel gave away the problem, and after a pressure check and top up I just left it alone in one case as the tyre was over half worn, and in the other I simply plugged it with a kit like Capitano has posted.
Certainly beats rapid deflation at speed and a knackered tyre and roadside recovery requirement.
It is also rumoured to help with small imbalance issues and can aid in creating an airtight rim/bead seal which is sometimes an issue after new tyres are fitted.

I used some of the Muckoff stuff in my Nexus tyres and it took care of my bead problems... every time I check my tyre pressure its never gone down for months, I think any type of this tyre gunk is good.

Always used Ultraseal and it's worked for me everytime. My Vstrom had two rear wheel punctures, one at 800 miles after buying the bike new and the other at 4,000 miles, both sealed instantly with Ultraseal, and of course permenantly. No need to have it patched or plugged. That tyre went on to provide 10,000 miles of trouble free use. Ultraseal is better than both a plug or patch in terms of strength and there's no speed restriction (well there is, 175mph once repaired) unlike the 80mph restriction of a patch or plug if professionally repaired. It never leaks again from the same place. We used it in the military in my unit (very successfully) and many many big fleets on our roads use it...Royal mail has it in 32,000 of it's vehicles for example. It works in any repairable punctures. Same rules apply regarding where the puncture occurs as to whether it needs to be junked of course. It doesn't affect wheel balance or valve life. Just one point...make sure your wheels are in balance before fitting Ultraseal as if the wheel is out of balance, it will make that out of balance feeling worse, but otherwise, no problems.

Oh...you can use it to repair an exsting puncture but it isn't really the best way to use it as it may not work as good. Many had done so with success though.

Thanks all for your replies. im inclined to try ultraseal or goop. the tyre was only recently fitted so would be annoying to have to replace.
