That reminds me, I remember seeing ads in the 1980s for some kind of record protector fluid that you were supposed to apply to your LPs and it would dry to a hard finish to protect the grooves like a laminate. Does anyone remember what that product was called? Better yet does anyone have records that were treated with it and if so, how do they sound today? I remember thinking it was a bad idea at the time and I never tried it.
It's called Last, still available (NOAF) and it has received several mentions in the threads. Let me see if I can find some of the threads.

That's it. I had totally forgotten about it until I saw the title of this thread and I couldn't seem to come up with the right search terms to find it. I'm amazed it's still around.

The claim is that it retards the deterioration of the record from playing it. I own records that are 60yrs old that have been played hundreds(maybe thousands?) of times that sound fantastic. So I’m trying to figure out why people think this is something they’d need.

That’s a really tough read, lots of big words and science. If what they’re saying is right then why do so many REALLY old records sound so good? I use my ears.Here's the science -

I love reading technical articles from before they even had a name for CD’s.
I’m certain LAST has some benefit to people who stare at their records through electron microscopes.

Nailed that!
I have a couple used albums with that Last sticker. I find that they are harder to clean, once dirty. Some kind of near-permanent surfactant which requires cleaning by hand and ultrasonic bath to remove. I don't treat any of my albums, just clean and dry them.
Not sure what the propriety product is, but it "lasts."

I've seen 12-inch 78-rpm shellac Columbia "Masterworks" albums with laminated records. The inner core appears like paper or thin cardboard. The outer surfaces shellac. The idea was to combine strength against breakage with smoother, softer, lower-noise playing surfaces. (Not suitable for use on older acoustical phonographs with steel needles and high VTFs.) Caution advised when cleaning these laminated discs as water can seep into the laminated core.

I have a few records I coated back in the 80s. Some of my best sounding. Never had to worry about too much dirt causing clicks and pops. I would recommend it but I think its a little expensive now.
I knew there was another product but I couldn’t remember the name. We sold Sound Guard at Lafayette Radio.
We had a salesman that was absolutely obsessed with it and spent every free moment coating his records in the sound room. It sprayed on and you spread it around with a Discwasher like pad.

Those are acetate recording blanks. Not as durable for playback as shellac and vinyl, worse than styrene.
