A few months back I put Bike-Seal in the tyres, Don't know if any of you blokes have seen the youtube vid on this but basically the owner of the company is banging nails and pointed chisels in the tyres spinning them and this stuff apparently stops the puncture straight away. So fooled by the vid I paid 30 quid for enough for the front and back tyres. Fast forward a few weeks and I get a 2mm nail in the back tyre, pulled it out and a few bubbles of the stuff came out but didn't stop the puncture, put some more air in the tyre, put the bike on the centre stand and spun the wheel in gear, still didn't seal. contacted the owner of bike seal and was told I did not understand the product Hmmmm and I had been rude to him in my email and don't contact him again...nice Contacted Infinity Motorcycles who issued me with a £30 voucher no quibble, good on em. Anyway don't waste your money on this stuff I know some of the other seals work but I went for Bike-Seal because it's water based and doesn't affect your rims, pity it doesn't work either. Rant over, this is my experience only, before I get sued.
