Treating records with LAST preservative

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.

I think LAST is an excellent product. I started using it in the 80's if memory serves. Absolutely no problems or issues on records that have been LAST treated for about 20 something years now.

I also use and would recommend their stylus cleaner.

Have Fun.

Perhaps, to a certain degree it depends on vinyl formulation. I am mostly interested in late 60s original American pressings and 70s original Japanese pressings but also some British from 70s and 90s.I do not intend to play them much if at all and just want to pass them on to my son.So, I would like to preserve the records for the next,say,70 years.My concern is that once it's done with the LAST it cannot be undone.

Aging and deterioration? My personal observation, and perhaps some of you may disagree, is that LP's simply do not age, deteriorate, or otherwise degrade when stored under reasonable conditions. If I am correct, then why add "Last" or any other chemical/preservative to the mix?

I'm one of those who bought LPs from Sdcampbell and can, indeed, vouch for their pristine condition and great sound. His use of LAST clearly has not deteriorated the sound in any way whatsoever. [PS, Scott... still waiting for that next list!]
