Puncture prevention/repair gloop

[stinkwheel]

Just wondering about peoples experience of these. Here's my experience from last week.

I pulled into a motorway services last weekend on my enfield bullet and as I was on the exit slip, noticed the handling was all screwey. Wasn't far enough down so I couldn't get back up to the services where I found the front tyre totally flat.

It would inflate but went down again after a few minutes. I decided some of that holts tyre foam was worth a try. You put it in then immediately ride away (it will just sit and pish out of the puncture if you don't get the wheels moving).

This was a good success, even with a tubed tyre, it inflated and stayed inflated. After about four days, it went down again. I topped it up with air and it stayed up.

Changed the tube yesterday. Contrary to popular belief, this didn't make an enormous mess. There was a moderate quantity of watery liquid in the tyre with small shreds of thin rubber which was simple to hose out then dry with paper towel and hoover out the rubber flakes.

What's interesting is a significant quantity of the foam/rubber shreds were in the tyre itself suggesting a fairly significant puncture in the inner tube that they leaked out through before it sealed. Thing is, the tube is still inflated the following day and I'm damned if I can find the location of the puncture by visually inspecting it or sticking it in a bowl of water. It's been replaced anyway. I think it went back down again because whatever reaction caused the foamy stuff to inflate the tyre had broken down but the "repair" was still effective.

In short, I'm impressed. I've decided I'll pre-treat the tubes in future. I've plumped for oko because a lot of the trials guys use it.

I'm also feeling my policy of not screwing the valve nut down against the rim was justified. I put the valve cap on then screw the stem nut up against the cap. When I checked, the valve was sitting at a slight angle in the rim which means it had crept round slightly. With the nut screwed down, this could have caused the valve to be ripped off.

I used the green one, gloop ?

Saved my bacon once, a small triangular bit of circuit board sticking out of the tyre showing the green sealer, may have been called "slime"...

I presently use the white oko stuff from the farmers supplies store locally. This has bits of rubber in it.

I've used ultra seal, which might now be branded as puncture safe. Their high speed claims and suitability for motorcycle tyres was the reason I used it.

This was only in tubeless car and bike tyres though. I don't think any of this type are recommend for use on tubed tyres, as the rubber crumb is supposed to jam then bond into the fairly thick tyre rather than trying to jam between a wafer thin tubes wall.

In short it works, and has sealed a pre existing puncture on a bike 180 rear. I squirted in the right amount and went for a ride, was still leaking. The puncture was too small, so bravery was required and I hammered a nail into the small hole, pulled it out and rotated the tyre on the centre stand and it sealed up immediately. Didn't have any further issues for the life of the tyre. I noticed a trail of blue spew at least once after where it had sealed another puncture, I hadn't even noticed it.


Apparently it also assists with dynamic balancing too, not sure if that's true as my wheels are always weighted properly.

I poured in the same gloop into the tyres on my Mondeo ST220 as all four tyres were leaking at the rim. That sorted it out nicely, and if I ever got a puncture in that I'd never have realised.

If I had any left it'd be in both current bikes, to save space carrying a pump and string kit. You can scoop it out and put it in new tyres when changing them over, paid tyre fitters probably hate it, it doesn't go everywhere but it's got to be messier than 'dry' tyres.

I might just buy some again.

In the past I used Gloop and Punctureseal in the past and have been pleased with it. It has obviously worked on a few occasions. Unfortunately now that I have tyre pressure sensors I can not use it as it buggers the sensors.
