i use small dabs of white lithium grease on my rails
I did this for many, many years.
White lithium grease is much lighter than the grease you are thinking of using, and it's very inexpensive at any auto parts store.
I'm a firm believer in using some light grease on the slide rails of a semiauto pistol, ESPECIALLY if the frame is aluminum, and thus more prone to wear by the steel slide.
I also use it on the frame unlocking lugs, which is a high pressure/wear spot on S&W metal framed semiautos.
I have ALWAYS thoroughly cleaned my pistols after shooting them, and reapplied some light grease to the frame rails and unlocking lugs.
I do this with all of my semiautos, and I've NEVER had a problem with a semiauto getting 'gummed up' from grease and crud.
A thin layer (small amount) of grease is all you need. It won't 'drain off', like many oils can, in storage.
