In this corner Groove Glide...

I agree completely with Albert. On Lp's on which I apply LAST, I follow the same procedure as LAbert using RRL fluid. LAST is meant to be a record preservative, as in preserving the vinyl. I think, and correct me if I am wrong, but GruvGlide is not intended to protect the vinyl perse but, rather, acts as a lubricant and in reducing static (better solved with a Zerostat, IMHO). I recall the LAST making a claim that it molecularly binds to the vinyl where as the GruvGlide does not.

I've used both and the Last is a great product. My turntable uses a felt mat and the static from it is problematic though. The record generally lifts the mat on removal from the platter. Then I need to peel the mat off the record and put it back on the platter. The Gruv Glide solves this problem. I've found that the absolute barest application provides all the benefits and I don't hear any degradation in my system. I also don't experience the gunk build up on the stylus that is often referred to. Of course, it's modest by Audiogon standards and I'd be foolish to think it would pick up the subtle nuances of a system like Alberts. I have tried two other mats previously that degraded the sound IMO. Simply put, the music lost whatever it is that makes my toe tap or my foot keep time with the music. I've own a Zero Stat and used it religiously until I discovered Gruv Glide. It saves a lot of time (especially when I have a listening partner) and I experience no ill effects from its use. YMMV and all that. A little science never hurts.

Years ago (15-20) I used LAST on my records and still play them with no ill effect.

I was just looking at one of my LAST stickers last night (the little dot on the record lable after you apply LAST) and wondering if there would be an improvement in sound if I had not treated it after all these years, as I was young and inexperienced in the ways of HI FI when I did use it, the posts above have made me feel better about that.

There was a time when I put Last on most of my records. There was a time when Lloyd Walker convinced me to use Gruv Glide. I used it on only about 10 records always after a thorough cleaning. After a one time listening, I hated the Gruv Glide thereafter. I then spent a good deal of time repeatedly cleaning my records to remove all traces of the Gruv Glide. I now understand that there is a Gruv Glide II which supposedly leaves less residue. I will never try it.

I have lately found that my Last treated records also benefit from a thorough cleaning on my Loricraft. I much prefer the sound having removed the residue of the Last.

In short, I think both products hurt my LP performance.

Thanks for all your information. I too have the static electricity lifting my mat with record. I need to experiment with a post-last rinse.
