Hi Joe ?Use nothing from a spray can on new knuckles. On the rep levers yes, but protect the leather from over spray. If sprayed?knuckles will become hard and crunchy. AMHIK?

It has been rebushed and repinned as well as getting new knuckles. I've been browsing the posts for the last month and enjoying them. I really appreciate the wealth of experience represented in these posts. I do wish there were a way to search the entire archive at once, but as far as I can see we are reduced to doing a month by month search. I've gone back 4 years and only seen McLube mentioned once. I have seen McLube recommended numerous places but never seen any info on actually using it. I have a can of 1708L. The can states that it can be used on jacks, wippens, and bridge tops as a graphite substitute. It also states that several coats may be required. I have several questions: how much is enough? Is burnishing useful? (I see little specs of dust dried in the film which may cause friction). If I were to use this on bridge tops, should this only be done without strings in place? I guess my final question should be: is this now the preferred treatment for jacks, or should I throw this can away and use something else? I am planning to use this in conjunction with teflon on the new knuckles. Thank you for your help. Joe -------------- next part -------------- An HTML attachment was scrubbed...
