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

"Last makes some very fine products. I just don't think the record preservative is one of them."
 Do you have reason / experience you could share and explain that could validate the above statement especially after calling it "goop". Curious , I have heard very few grumblings, but never an explanation beyond opinion. I get why some don't want to put anything on a clean record , I didn't at first either. But that doesn't mean Last is bad or goop which requires explanation beyond just not wanting to use it as a reason to knock it . I understand why many would not put anything on a clean record other than a clean well adjusted stylus but that's a personal choice not a reason that Last is " goop" and doesn't do what it's designed to do. 

I have used a loricraft to clean my records since the eighties myself. I clean every album new or used before I will play them. Back in the nineties when I was cleaning up on cheap vinyl prices, I bought a collection of about 300 rarer records off a guy who kept his records very clean and most all of them had the last treatment and the sticker applied to the labels they gave you. It certainly never made them sound better, but , they certainly don't play with the signs of wear that albums that get played as much as they have .  I have treated many myself as well through the years also. So for my actual long term experience based opinion , I have seen zero negative reasons against and have 40 yr old heavily played  records that don't play like they were played as much as i know they were. Being a preservative it's meant as a long term thing ,  anyone expecting instant gratification isn't going to find it . To each his own as they say.....
Every record I've bought used with a Last sticker on it sounded very quiet. It's pretty much a guarantee the record has been treated well. I believe it works but I have no direct experience other than that.
Yes, can be a touch quieter too with some pressings. I also suggest MA Recordings inner sleeves.
And if you use tape deck treat the heads with LAST head treatment before each play. Not substitute for head cleaning of course but a complement. I do it and there is virtually no head wear after thousands of hours of play. I do use best tape and clean the playback head after every 15 hours of play.
Perhaps it was a case of user error . . . 

but many, many years ago I tried the stuff on quite a few records and found, after time, that they sounded worse (clicks, pops, etc. that were *not* present when the records were treated).

I've stayed away from that stuff and for years have relied on my Loricraft and proven cleaning fluids.  Very happy with that arrangement.
