FWIW -
I just picked up some Moly 60 paste. PN# 08734-0001, at the local Honda dealership in Lynnwood , WA per one of CDT's tuning articles - they stock it. It comes in 1 1/4" x 6" , 3 oz. tubes for small grease guns. The price has gone up from $9 to $12-13 per tube depending on the dealership. Don't know how this compares to Maccarri's as I didn't see size in ounces on his website. If you just need a small amount, NAPA auto parts stores have Moly paste with graphite in small tubes. You can check it out at the NAPA site on the web under lubricants. My local store has three different types - their brand and two others - the NAPA website only shows one.
Also, if you are in the Seattle area, I checked out the mention of Adventure Sports (a well stocked gun shop) in the 23300 block on Highway 99 in Edmonds from one of the airgun forums - don't remember which one. They have airgun pellets - mainly Beeman tins, Crosman premier boxes of 625, along with a few others; quality airguns (Gamo, Beeman, RWS, Theoben, etc); airgun scopes (Leopold, BSA, Bushnell, etc); lubes and cleaning supplies; and standard gun lubes like Remoil. Knowledgeable guys, well stocked store, no website.
