Hi Rick
During last summer, we had a bloke turn up in a van at our local meet he was putting some sort of liquid into the tyres which sealed the hole from nails screws etc. I used to be in the Motor trade in the 70's and I asked this guy if it was a similar product to what was used then he said it was but they had improved it. I cannot remember the name of the new stuff, but the one from the 70s was green and slimey and it was called "OKO". He was charging around £30.00 for both front and rear wheels fitted.
