the club sell WURTH HHS GREASE with PTFE, i've tried to find a decent supplier so i could buy a few cans to stock up, but to be fair one can is going to last for ages, and the clubs prices are so cheap, that i didnt bother looking too far.
see the mechandise link at the top of the forum, and pm pete_g40 / hayesey or another member of the admin team =]
