Groove-Glide vrs Last Record Preservative


I'm looking for opinions on the different qualities and characteristics of Groove-Glide vrs Last Record Preservative.
I personally have only used Last. I think I hear a smoothness (more analoguey?) after using it. I've taken to opening new albums, applying Last, waiting five minutes, playing the record, then cleaning my stylus and cleaning the record and putting it in a new sleeve. Mostly I use the product for the promise of being able to listen to the album once per year for the rest of my life without it losing fidelity.
I'd especially like to hear from someone with experiance using both products, comparing and contrasting. Anyone know of any DIY similar products? Why is this stuff so expensive (other than the fact that they can charge anything and we'll buy it?) I'd love to buy a 55 gal. drum and break it down it 5 oz. bottles to sell on AudiogoN at about a buck a pop!

how many plays does one think a record can handle before it looses it fidelity? with the correct cartridge and setting? some say hundreds...
I have used Gruv-Glide since 1981. One application enhances the sound for many plays. I like it better than LAST because it is so easy to use, and does not alter the Vinyl Molecule. In fact you can wash it off if you don't want it on the record, and it rinses completely.

LAST is also a good product. I hear more of a sound improvement from GRUV-GLIDE. By the way they spell it GRUV-GLIDE, they have a website you can view under "G" of the manufacturers listings.

Hope this helps.
I used last for a number of years, but after using the Nitty Gritty on several Last treated products, the sound was degraded substantially. I have been using the Gruv-Glide product for about a year. It doesn't hurt, but I am not certain how much it helps. I believe that it and Last are 2 completely different products with different purposes.
Dear hlfoyd,

You are exactly right! LAST is a preservative & actually changes & alters the vinyl structure permanently.

GRUV GLIDE is a dry record treatment that enhances sound, completely gets rid of static, and enhances the trackability of the stylus in the groove. It does not alter the vinyl and can be washed off completely if you desire.

GRUV GLIDE is also much easier to use & way more economical
IMHO.

Hope this helps.
