hi, for your information and for those that took an interest in the postings 'more usefull than WD 40 ??' I started in 09 June 04; the aerosol lubricant I found was in a Asda supermarket. it's: 'TF2 lubricant spray with Teflon. at £1.90 for a 450ml a can, it's less than half the price found at halfords and other car shops I contacted. john west
