The Lifespan of an LP?

i've heard examples of records that sounded trashed even played with a line contact, but on an ELP, with the tracking laser point carefully dialed in, it was often possible to find a spot with less wear than the rest of the groove, and the record's audible grade improved to VG or better. for those here rich enough to get an ELP, as finicky and impractical as they are, i have not heard any better reproduction of trashed records than on that miracle machine. just make sure the record is lab-grade clean before you put it on, or you and your tweeters will be sorry. 

L.A.S.T. [Liquid Archival Sound Treatment] is a fluorocarbon-based record preservative and lubricant and leaves no discernable residue, adds no noise, and in my experience has rescued many a garage-sale disc from the trash. overall noise levels dropped by at least a record grade, formerly distorted records became more listenable. i am no chemist but it is claimed to add more elasticity to the top layer of molecules [supposedly 10 deep] in the vinyl groove, which help to reduce distortion and noise. one warning, NEVER leave the bottle cap off of it, as it will evaporate and it ain't exactly cheap.
