What Grease to use on my Mirror Slides. Grease is the Word

[BlackWidow]

I am wanting to replace the grease on my LX200GP to aid in the reduction of mirror slop. I have all the Peterson Mods on my scope so the slop is not too bad. I am also wanting to improve the slop in a friends ETX125. I just wanted to know what grease is used :question:

I am guessing that somthing like White PTEF Lubricant would be the go. It can withstand temps ranging from -65 to +650 whilst maintaining adhesion. I just want to be sure before applying anything in case I am about to do damage without knowing it. Any advice from those in the know would be great.

The PTEF that I already have is a Star Brite marine formula that I have used in boating applications.

Dupont make a product called "Kryox" or "Krylox" or something like that.
Supposed to be the business.
"Casstony" knows.

Mardy, you need a damping grease like this.

I have had a look at both suggestions given and it seems that the stuff I have is pretty much the same. Is not effected by water, very thick and sticks well in temps up to 650 Deg F. My main concern was that some products can effect plastics and metals over a long period. Your help has been great as I have been able to see that some of the products are branded as a special item when in fact some are very much the same. PTEF seems to be a reg name for polytetraflouroethylene. It is much the same as the non slip coating on frypans but in a diff medium and clear in colour. It seems to be sold under many different forms mixtures and names. I now feel confident that the stuff I have will do the Job..
