    I have a collection of gun greases ,high temp lubes, etc from over the years. I thought I would try some 40% moly paste (that I use on the final drive splines of my 2 WD Ural w/side car. What a big difference. I did have the gunslick graphite/moly grease, but this is way better. Good for 750 degrees, so it should be OK. Really slick now, like it has been cycled a few thousand times.

    Yup agreed good moly grease is a very good.
    Careful with anything containing any graphite. Getting even a trace amount in the bore will accelerate erosion.

    Did you burnish it in and then clean it off and lube per normal. That's what I did. I used tungsten disulfide which is extremely similar and some say better. Apparently the reason tungsten disulfide didn't catch on as much was because it used to be so much more expensive that moly, though that's no longer the case. Either produces excellent results because they are dry lubricants that work their way into the micro porosities of materials and stay there under adverse conditions. Great stuff!

    I did not know about the graphite in the bore issue-but I never put enough on the lugs to get into the chamber or bore (before when I did use it on the lugs). Besides it was time for a good cleaning with JB bore cleaner and some bore snakes.

    I think I still have some Moly in the garage. I used regular gun grease and it made quite a difference in the action operation. Just a little dab on each lug.

    The Honda moly is about the same as the stuff I have at approx.50- 60% moly. The grease that you buy from autoparts store is less than 5% moly. Very significant percentage.

    FYI, powdered molybdenum or tungsten disulfide can easily be purchased in 100% pure powder form and you can mix your own goop using some high quality synthetic oil or grease.

    Yep. You can simply Google either of the materials and find various sources, but here are some links:

    1 lb bag (way more than you'd ever need): http://www.lowerfriction.com/product-page.php?categoryID=1 Good info on the site.

    And they have a spray as well, though it can be messy for some uses: http://www.lowerfriction.com/product-page.php?categoryID=23

    Thanks for all the info. The small bottle (4oz) I have of 60% moly will last me the rest of my life. However I see the Tungsten Disulphide (2oz) is added to the gearboxes of of Can-am UTV's . I might go by the Polaris shop and see if I can buy a 2oz bottle.
