One thing that Gus didn't explain to us was what sort of rails he's talking about. If they are ball-bearing slides, or even the kind with small wheels, it is actually kind of surprising that they would need any lubrication at all. Is it possible that these are just metal-on-metal telescoping slides

John Deere Cornhead Grease. It's specifically designed for bearings in low heat/low pressure situations. It is a thin grease that should be used sparingly. If you have a Ferguson, JD, ford N or 100's series tractor that has a leaking steering box, it works well there too. :-) ___
