Goop

[lemonjelly]

at the recent ILOC Int'l I was recommended GOOP  as a preventative puncture solution used by the Post Office,i ve ordered some,its suitable for tubeless or tubed wheels,and used by the Post Office,seems once installed if a puncture occurs the small particles of rubber and other components seal the hole.Has anyone had experience of this product?

i wonder if this was the stuff we found in the tyres of my trophy which i bought from the uk nearly two years ago. i took the bridgestones off and replaced them with roadsmarts and when we removed the bridgestones there was this gooey, greenish jelly like stuff oozing all around the inside. there was lots of it, too. the tyre people had never seen anything like it. i havent put anything in to replace it and there is no more shimmying of the front end at low speeds and no more high frequency vibration of the fork in its vertical travel at high speed on some surfaces. this was a nasty sensation. i think the goo caused these problems not the bridgestones.

Henry, if it was green it was Slime, which does indeed fill little 'oles from the inside pretty well, but also totally covers the inside of tyres and wheels with green sticky muck that is really hard to remove. All the bike shops here have signs up saying how much they charge for fixing tyres full of Slime, usually $50-$70 extra just to clean the disgusting stuff off.
Goop, on the other hand, is crystal clear. It works very well for repairing running shoe soles, some formulations of it have very high internal cohesion and make excellent contact cement substitutes (that don't require both surfaces to be tacky and brought together in perfect alignment, considerable setup movement is possible). But even straight from the tube it is VERY viscous, like stiff pitch, and I don't even know how you'd get it into a tyre. Also it air dries so you'd get a big lump of heavy Goop hardening at the lowest point of a tyre parked overnight... :-[
Unless Goop has come out with a different formulation for tyres, I suspect it would be an absolute disaster in motorbike tyres.

The green goop is paranormal ectoplasm. You've been slimed. You know who to call ...

On the other hand, it could be lime jelly. Your bike may have previously belonged to lemonjelly's brother.

well Goop says its not Latex and washes off

full description is on item no below 500ml bottle for two tyres though I might hold off installing it and save for the kids push bikes first.

ha ha, has this got anything to do with flubber or whatever it was called?

actually it really was a pig to clean the stuff off - we used loads of paper towel and really had to work at it. i don't think i would bother with puncture protection here, i can't remember the last time i had a flat.

Wot he said.  I last had a flat about 20 years ago.  We all get recovery in with our insurance now, and if not then a can of Finilec will get you home, and most importantly you will know your tube has been punctured, been weakened and needs fixing (properly) or replacing.

LJ, what about wheel balance? The Gloop will do you no good there. Maybe OK for pottering around posting letters, but for higher speed work, it makes no sense whatsoever to me.  Hag.

Hmm, one of my mates used to rave about goop. And, on other occasions, Oko. And Slime.

Not saying I was suspicious of his critical faculties but he did have magnets on his fuel hose, had a fuel cat in his petrol tank and bought "herbal" slimming pills for his mrs.

Come to think of it, it was almost always him that had the mechanical issues when we were out for a fang.

I have used Finilec a lot.

When racing karts we had to have bolts through the rims to keep the tyre on the rim. A little squirt in each kept the pressure perfectly.

It is also good for sealing alloy rims but I would not use it day to day. Only one way to mend a puncture....Spock it.

Think I will save it for the kids bikes,as they happen a lot,so money well spent,a right pain especially when they are cutting the hedgerows,I agree about balancing and they are a rare occurance,

Cheers all for input.

True if the stuff is allowed to set while the wheel is stationary. But liquid in a tyre will self-balance as long as it stays liquid. That's why the manufacturers of this kind of product say to squirt it into the tyre and stard riding/driving straight away.

well, i don't know if the green, jelloid, extra-terrestrial remains in the wheels of my trophy had ever been liquid, but it sure affected the handling and especially stuffed up the front fork damping action on many surfaces at over 210 kph, so much so that i had to slow down to under that speed to get it under control. it kind of 'fibulated' for want of a better word.
when i changed the horrible bridgestones for a set of roadsmarts, the improvement was dramatic and i have had no problems with the front end since (and i've seen 250 on the clock quite a few times since, often on the same surfaces where i had problems before).

i have used one of these puncture repair aerosols on my susi samurai and it worked perfectly, but that has difficulty getting to 130 (pretty scary at those speeds, too).
