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

Blueanger,  I never buy the 2 oz. bottle and never counted the number of records, but know how you can find the answer as to the number of records you can expect to treat per bottle.  You can call Last and they will tell you or you can call a retailer like Music Direct.  With each bottle a supply of applicators and sheets of sticky labels are supplied.  Every record you treat gets a sticky label and it is uncanny how the number of labels always works out to be just enough to last through a bottle of the stuff.  So it is a simple matter to count the number of sheets supplied with each bottle.  There are 16 labels per sheet.  The Last Factory can be reached at 925-449-9449 or www.thelastfactory.com.  Or www.musicdirect.com
Thanks for the link to Larry Archibald's Stereophile review, has2be. I had seen those microscope pics of Last treated and untreated grooves, but it was years ago. Michael Fremer has also reviewed Last, and is an enthusiastic endorser. You know who else is? The snake oil suckers at The Library Of Congress, who were early adopters of Last Record Preservative. As my momma use to say about anything uttered, consider the source.
I can't find this answer. How many records does a 2 oz bottle treat??? Thanks for everyones opinion. I might just treat my most frequently played records

Here it is straight from the source........

bdp24 - When I used Last, I first cleaned the records on a Nitty Gritty 2.5i.  If I recall correctly, I also used a fluid named "First" which was a "pre-cleaner" and, I think, was made by the folks who made Last.

On Last-treated records, the surface noise I heard developed only some months later.  

Who know the reason(s)? Maybe I got a bad batch?  I own several thousand LPs and haven't run into this problem before or since.  In any case, I now steer clear of Last.
