The first question is prompted by lurking here - where to get a digital tyre gauge? Standard advice seems to be "Dick Smith", but their online catalog shows no such item. I assume it was dropped a few years ago. Google doesn't help for Aussie retailers, and my other obvious candidates don't show it either. Any other ideas? The second question relates to hints I got from the other bike lists, but rarely mentioned here. I'm looking for some "dielectric grease" - supposed to be excellent on electrical contacts as it prevents corosion, is non-conductive, but critically has very low sheer strength so is safe to use wherever electrical contact is necessary - ie, it should be smeared all over your connectors. Google it for more info. It appears 3M make it ([URL]http://tinyurl.com/59f9q[/URL]) and plenty of others do too, but I'm struggling to find local retailers for this. Any ideas, oh wise ones?
