Just read it, YOU ALL SHOULD.
Being an auto parts guy, I already knew ATF was good stuff. Think about it, it's used in automatic transmission, but did you know Dodge has used it in manual boxes since the '70s?
Ok, think more, won't shear off sliding gears, handles 400hp Hemi's, and sits in the box for 15 or 20 years or so before getting changed. Is that a long term storage or use? Yep.
Grease is nice on BCG's, but if you wipe it down after every shoot, a small bottle with ATF is a lot easier and better to handle than a tub or tube of grease.
ATF is the way to go. Priced like Rem Oil, it should be $14.99 a quart. Quick, save $10 and get Dexron III for $4.99 at your local auto parts supplier!
Just remembered, my neighbor moved last year and gave me half a gallon free.
