grease advice needed

As a brass musical instrument player, this discussion of lubricants is deja vu all over again. Brass players go on and on ad nauseum about what the best valve oil or slide grease is, with no one putting forth any convincing arguments. There are literally hundreds of products out there, petroleum-based and synthetic. I've got a couple of thse old Sony displays--and I've never done a thing to lubricate their bases--they usually just get set in a single position and left that way for years. If I had one that was getting sticky, I'd probably just zap it with some silicone aerosol. (FWIW, I lube my tuba slides with a mixture of mineral oil and anhydrous lanolin and lube the valves with triple-filtered white kerosene (odorless). It's cheap and it works.) Cheers, Chuck
