Tyre sealant - any good?

[BishBashBosh]

OKO for me , never had a problem with it.

 

Lots of hawthorn in my garden so the ride on was getting punctures every couple of weeks. I used 2/3's of the recommended amount of OKO, and 7 years later I've yet to have another puncture. I used the off road version.

 

The only inconvenience is when giving the tyres their twice yearly pump up. You need to have the valve at the top of the tyre to stop any sealant gungeing the valve, and ideally leave it in that position for a while before topping them up. Bit of a pain, but twice a year's not too bad.

Unlike lurkalot, and I am not trying to create an argument, 

Me neither,  I can only offer what I have observed over the last 41 years of repairing garden machinery.  The amount of machines, mainly Countax that have flat tyres after being stored for the winter, customer then requests that we repair punctures.  Then we find they're full of that stuff already.  Tyres are flat or soft but can't be pumped up, because the valve is blocked, Sometimes the valves won't come out, you then have to rip the valve out and get a face full of gunk.  So I guess my response is from a fitters perspective rather than a end users.
