LAST has been out for many years and works quite well. I've used it many times. One thing I don't like about LAST is that once applied it won't come off, and it permanently changes & affects the vinyl. So if you don't like the sound you are stuck. It's also not real easy to apply. None the less good stuff.
I have been using GruvGlide and like that better.It does not affect or change the vinyl, record sound is definitely improved, very economical and easy to use. They are in the Audiogon manufacture directory under "G" or www.gruvglide.com (also stereophile recommended for years).
Hope this helps, and happy listening!
