Treating records with LAST preservative

Tom said it all. I do however use Gruv Glide although at a much lesser level than the instructions say. It's a must for Linn owners because without some type of anti-static the felt mat will lift with the record in the winter which is a major annoyance. I don't know if it will damage the vinyl with time but doubt it. It's easily removed with a normal, quick wet cleaning on my machine. At least that's been my experience.

I remember reading that The Library of Congress uses Last Record Care products to preserve vinyl records (Also, some time ago they purchased several top-of-the-line Simon York turntables to play their collection and transcribe many of them to digital. They must have done their research as I am sure they have "one-of-a-kinds" that are priceless.

I go with the "If it ain't broke don't fix it" crowd.
Billions? of records have never seen Last. And most of the ones that avoid: being scratched (Last ain't gonna help that), and being played on a TT with a really damaged Cartridge (Last ain't gonna protect from that either) are in good shape.
Keep 'em clean and use a good cart with a perfect needle and your records will last without Last.

An interesting "mixed bag" of opinions here. To add one more voice, I've been using LAST preservative on my vinyl records for about 30 years, and have had uniformly good results with it. Of course, I thoroughly wet-clean my LP's first, using a Nitty Gritty record cleaning machine, and then apply LAST. During the past several years, I've sold about 1/3 of my record collection to people who frequent Audiogon, and nearly every one of them has written me to comment about the excellent condition of the records. The great majority of those LP's had been treated with LAST.

My experience is identical to Sdcampbell. Of my (approx.) 6000 LP’s there are only a hand full that are not treated with LAST.

I like the product and in comparisons with Groove Glide, preferred LAST.
