Is the Last Record Preservative system a worthwhile investment?


I take great care in my record collection.
1. I have a manual record vacuum cleaning machine. I also use an enzyme cleaner on a few really dirty ones.
2. I replace all paper sleeves with plastic ones.
3. I use groove glide on only the records in really bad shape. Around 1 percent.
4. I use a record jacket to protect the covers.
5. I meticulously keep the stylus clean.
6. Use a brush everytime I play a record.
  My question being is; will the Last system actually improve the sonics even after all the care I put in to my collection?
How much time is involved treating a record? How much per record does it cost if I buy the larger treatment kits? Id like to hear your experiences with this product. I have close to 3000 records. My analogy is like a great movie that I have never seen. Wow you just now saw that? Will I have an aha moment using the Last system like oh wow, I should have seen that movie years ago. Lol

I have used it on many Lp's over many years ago, but noticed no improvement over my other untreated records. Just my opinion...
I'm in favor of keeping LPs clean. Really, really clean, such as can be achieved using a good ultrasonic cleaner. Cleanliness is best the LP preservative, imo, and I don't see any need or advantage to then putting goop on a clean LP.
I very much agree with cleanliness cleeds (I own a VPI HW-17F, and am putting together a DIY USC), but Last is not "goop". It is a very thin liquid, which when applied to an LP bonds molecularly with the vinyl, preventing the fracturing of the vinyl's molecules. Last creator Walter Davies is not just a chemist, but a long-time audiophile, engineer, and hi-fi retailer. I bought my first big system (Magneplanar Tympani's bi-amped with ARC electronics) from Walter in 1973. He's a fantastic guy, and Last Record Preservative a great product!

I'm familiar with the product. I think it is a cure in search of a disease.

I don't doubt that he's a good guy, and Last makes some very fine products. I just don't think the record preservative is one of them.
If your hearing and system are good enough there is a very slight improvement in clarity. Good test. But yes, the LAST was not designed for that purpose, it's a bonus. Second treatment does not improve sound quality, at least I don't hear it.
I use Okki Nokki cleaning machine in reverse to treat records with it, three revolutions.
